Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	1. Nature of Business Nature of Operations Yunhong CTI Ltd. (formerly CTI Industries Corporation), its former subsidiaries - United Kingdom subsidiary (CTI Balloons Limited), Mexican subsidiary (Flexo Universal, S. de R.L. de C.V.), and German subsidiary (CTI Europe GmbH); as well as current subsidiary CTI Supply, Inc. (collectively, the “Company”) (i) design, manufacture and distribute metalized and latex balloon products throughout the world and (ii) operate systems for the production, lamination, coating and printing of films used for food packaging and other commercial uses and for conversion of films to flexible packaging containers and other products. As discussed in Note 19 Discontinued Operations, effective in 2019, the Company determined that it was exiting CTI Balloons Limited and CTI Europe, and during 2021 sold its interest in Flexo Universal. Accordingly, the operations of these entities are classified as discontinued operations in these financial statements.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of Yunhong CTI Ltd., its wholly owned subsidiary CTI Supply, Inc. and former wholly owned subsidiary CTI Balloon Ltd and its former majority owned subsidiaries, Flexo Universal and CTI Europe. All significant intercompany accounts and transactions have been eliminated upon consolidation. As discussed in Note 21 Discontinued Operations, effective in 2019, the Company determined that it was exiting CTI Balloons Limited and CTI Europe, and during 2021 sold its interest in Flexo Universal. Accordingly, the operations of these entities are classified as discontinued operations in these financial statements. Variable Interest Entities The determination of whether or not to consolidate a variable interest entity under U.S. GAAP requires a significant amount of judgment concerning the degree of control over an entity by its holders of variable interest. To make these judgments, management has conducted an analysis of the relationship of the holders of variable interest to each other, the design of the entity, the expected operations of the entity, which holder of variable interests is most “closely associated” to the entity and which holder of variable interests is the primary beneficiary required to consolidate the entity. Upon the occurrence of certain events, management reviews and reconsiders its previous conclusion regarding the status of an entity as a variable interest entity. Foreign Currency Translation The financial statements of foreign subsidiaries were translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities, the historical exchange rate for stockholders’ equity, and a weighted average exchange rate for each period for revenues and expenses. Translation adjustments were recorded in accumulated other comprehensive income (loss) as the local currencies of the subsidiaries are the functional currencies. Foreign currency transaction gains and losses were recognized in the period incurred and are included in the consolidated statements of operations. This issue became moot with the elimination of all foreign subsidiaries between 2019-2021. Use of Estimates In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the amounts reported of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period in the financial statements and accompanying notes. Actual results may differ from those estimates. The Company’s significant estimates include valuation allowances for doubtful accounts, inventory valuation, deferred tax assets, goodwill and intangible asset valuation, leasehold assets and liabilities, Preferred Stock deemed dividends and beneficial conversion feature values, and assumptions used as inputs in the Black-Scholes option-pricing model. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits and short-term investments with original maturities of three months or less. Accounts Receivable Trade receivables are carried at original invoice amount less an estimate for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by identifying troubled accounts, evaluating the individual customer receivables through consideration of the customer’s financial condition, credit history and current economic conditions and use of historical experience applied to an aging of accounts. A trade receivable is considered to be past due if any portion of the receivable balance is outstanding for a period over the customer’s normal terms. Trade receivables are written off when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using standard costs which approximates costing determined on a first-in, first-out basis, to reflect the actual cost of production of inventories. Production costs of work in process and finished goods include material, labor and overhead. Inventory is not recorded in excess of net realizable value. Property, Plant and Equipment Property and equipment are stated at cost. Expenditures for maintenance and repairs are charged to operations as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized on a straight-line method over the lesser of the estimated useful life or the lease term. The estimated useful lives range as follows: Schedule of Property Plant and Equipment (in years) Building 25 30 Machinery and equipment 3 15 Projects that prolong the life and increase efficiency of machinery 3 5 Light Machinery 5 10 Heavy Machinery 10 15 Office furniture and equipment 5 8 Intellectual Property 9 15 Leasehold improvements 5 8 Furniture and equipment at customer locations 1 3 Light machinery consists of forklifts, scissor lifts, and other warehouse machinery. Heavy machinery consists of production equipment including laminating, printing and converting equipment. Projects in process represent those costs capitalized in connection with construction of new assets and/or improvements to existing assets including a factor for interest on funds committed to projects in process of $ 108,000 220,000 Stock-Based Compensation The Company has stock-based incentive plans which may grant stock option, restricted stock and unrestricted stock awards. The Company recognizes stock-based compensation expense based on the grant date fair value of the award and the related vesting terms. The fair value of stock-based awards is determined using the Black-Scholes model, which incorporates assumptions regarding the risk-free interest rate, expected volatility, expected option life, and dividend yield. See Note 14 for additional information. Fair Value Measurements Current professional accounting guidance applies to all assets and liabilities that are being measured and reported on a fair value basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market. The requirements prescribe a fair value hierarchy that has three levels of inputs, both observable and unobservable, with use of the lowest possible level of input to determine fair value. A Level 1 input includes a quoted market price in an active market or the price of an identical asset or liability. Level 2 inputs are market data other than Level 1 inputs that are observable either directly or indirectly including quoted market prices for similar assets or liabilities, quoted market prices in an inactive market, and other observable information that can be corroborated by market data. Level 3 inputs are unobservable and corroborated by little or no market data. The carrying value amounts of the Company’s cash and cash equivalents, accounts and notes receivable, accounts payable and other current liabilities are reasonable estimates of their fair values due to the short-term nature of these instruments. The fair value of business segments (as needed for purposes of determining indications of impairment to the carrying value of goodwill) is determined using an average of valuations based on market multiples and discounted cash flows, and consideration of our market capitalization. See Note 5 for further discussion. Valuation of Long Lived Assets The Company evaluates whether events or circumstances have occurred which indicate that the carrying amounts of long-lived assets (principally property, plant and equipment) may be impaired or not recoverable. The significant factors that are considered that could trigger an impairment review include: changes in business strategy, market conditions, or the manner of use of an asset; underperformance relative to historical or expected future operating results; and negative industry or economic trends. In evaluating an asset for possible impairment, management estimates that asset’s future undiscounted cash flows and appraised values to measure whether the asset is recoverable. The Company measures the impairment based on the projected discounted cash flows of the asset over its remaining life. Deferred Financing Costs Deferred financing costs are amortized over the term of the loan. Upon a refinancing, existing unamortized deferred financing costs are expensed. Income Taxes The Company accounts for income taxes using the liability method. As such, deferred income taxes reflect the net tax effects of temporary differences between carrying amounts of assets and liabilities for financial reporting purposes and the amount used for income tax purposes. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain. Deferred tax assets and liabilities are measured using enacted tax rates expected to be in effect when the anticipated reversal of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance when management cannot determine, in its opinion, that it is more likely than not that the Company will recover that recorded value of the deferred tax asset. The Company is subject to U.S. Federal, state and local taxes as well as foreign taxes in Mexico (through October 2021). U.S. income tax expense and foreign withholding taxes are provided on remittances of foreign earnings and on unremitted foreign earnings that are not indefinitely reinvested. We utilize a two step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not the position will be sustained upon tax authority examination, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. See Note 10 for further discussion. Revenue Recognition On January 1, 2018, we adopted Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers Net sales include revenues from sales of products and shipping and handling charges, net of estimates for product returns. Revenue is measured at the amount of consideration the Company expects to receive in exchange for the transferred products. Revenue is recognized at the point in time when we transfer the promised products to the customer and the customer obtains control over the products. The Company recognizes revenue for shipping and handling charges at the time the goods are shipped to the customer, and the costs of outbound freight are included in cost of sales, as we have elected the practical expedient included in ASC 606. In most cases, the Company has a single product delivery performance obligation. Accrued product returns are estimated based on historical data and evaluation of current information. The Company provides for product returns based on historical return rates. While we incur costs for sales commissions to our sales employees and outside agents, we recognize commission costs concurrent with the related revenue, as the amortization period is less than one year and we have elected the practical expedient included in ASC 606. We do not incur incremental costs to obtain contracts with our customers. Our product warranties are assurance-type warranties, which promise the customer that the products are as specified in the contract. Therefore, the product warranties are not a separate performance obligation and are accounted for as described herein. Sales taxes assessed by governmental authorities are accounted for on a net basis and are excluded from net sales. A disaggregation of product net sales is presented in Note 16. Research and Development The Company conducts product development and research activities which include (i) creative product development and (ii) engineering. During the years ended December 31, 2022 and 2021, research and development activities totaled approximately $ 200,000 206,000 Advertising Costs The Company expenses advertising costs as incurred.

New Accounting Pronouncements	4 . New Accounting Pronouncements Recent Accounting Pronouncements Credit Loss In June 2016, the FASB issued authoritative guidance to replace the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. For public entities, the guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, which for the Company was the first quarter of fiscal 2021. The adoption did not have a material impact on its consolidated financial statements. Income Taxes In December 2019, the FASB issued authoritative guidance that simplifies the accounting for income taxes as part of the overall initiative to reduce complexity in accounting standards. Amendments include removal of certain exceptions to the general principles of Accounting Standards Codification 740, Income Taxes. The amendments also include simplification in several other areas, such as recognition of deferred tax assets on step-up in tax basis in goodwill and accounting for franchise tax that is partially based on income. For public entities, the guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, which for the Company was the first quarter of fiscal 2021. The adoption did not have a material impact on its consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	5. Fair Value Disclosures U.S. GAAP clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. U.S. GAAP also requires that a fair value measurement reflect the assumptions market participants would use in pricing an asset or liability based upon the best information available. U.S. GAAP establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows: ● Level 1 ● Level 2 ● Level 3 A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of the input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Commitments	12. Commitments Operating Leases We adopted ASC Topic 842 (Leases) on January 1, 2019 using the modified retrospective method. This standard requires us to record certain operating lease liabilities and corresponding right-of-use assets on our balance sheet. We elected the package of practical expedients available for expired or existing contracts, which allowed us to carryforward our historical assessments of whether contracts are (or contain) leases, as well as lease classification tests and treatment of initial direct costs. We also elected to not separate lease components from non-lease components for all fixed payments, and we exclude variable lease payments in the measurement of right-of-use assets and lease obligations. Upon adoption of ASC 842 we recorded a $ 2.8 1.1 1.7 We determine if an arrangement is a lease at inception. Most of our operating leases do not provide an implicit rate of interest so we use our incremental borrowing rate based on the information available at the commencement date to determine the present value of future payments. We lease various assets in the course of ordinary business including warehouses and manufacturing facilities, as well as vehicles and equipment used in our operations. Leases with an initial term of 12 months or less are not recorded on the balance sheet as we recognize lease expense for these leases on a straight-line basis over the lease term. The depreciable life of assets and related improvements are limited by the expected lease term, unless there is a reasonably certain expected transfer or title or purchase option. Some lease agreements include renewal options at our sole discretion. Any guaranteed residual value is included in our lease liability.

That model incorporates various assumptions in the valuation of stock-based awards relating to the risk-free rate of interest to be applied, the estimated dividend yield and expected volatility of the Company’s Common Stock. The risk-free rate of interest is the U.S. Treasury yield curve for periods within the expected term of the option at the time of grant. The expected volatility is based on historical volatility of the Company’s Common Stock. The valuation assumptions we have applied to determine the value of warrants granted in 2021 and 2020 were as follows: Historical stock price volatility: The Company used the weekly closing price to calculate historical annual volatility. Risk-free interest rate: The Company bases the risk-free interest rate on the rate payable on US treasury securities with a similar maturity in effect at the time of the grant, which was 3.80% 0.30% Expected life: The expected life of the warrants represents the period of time warrants were expected to be outstanding. The Company used an expected life of 5 Dividend yield: The estimate for dividend yield is 0% Estimated forfeitures: When estimating forfeitures, the Company considers historical terminations as well as anticipated retirements.

Discontinued Operations In July 2019 management and the Board engaged in a review of CTI Balloons and CTI Europe and determined that they are not accretive to the Company overall, add complexity to the Company’s structure and utilize resources. Therefore, as of July 19, 2019, the board authorized management to divest of CTI Balloons and CTI Europe. These actions were taken to focus our resources and efforts on our core business activities, particularly foil balloons and ancillary products based in North America. The Company determined that these entities met the held-for-sale and discontinued operations accounting criteria. Accordingly, the Company reported the results of these operations as discontinued operations in the Consolidated Statements of Comprehensive Income and presented the related assets and liabilities as held-for-sale in the Consolidated Balance Sheets. These changes were applied for all periods presented. The Company divested its CTI Balloons (United Kingdom) subsidiary in the fourth quarter 2019 and CTI Europe (Germany) subsidiary in the first half of 2021. In connection with management’s intentions to simplify these operations and organizational structure, we identified write-offs of $ 1.75 1.0 67,000 8,000 In October 2019, we determined that we would not renew our Trademark License Agreement with SC Johnson when it expired on December 31, 2019. Under this Agreement, we were licensed to manufacture and sell a line of vacuum sealing machines and pouches under the Ziploc® Brand Vacuum Sealer System. The terms of the Agreement included a run-off provision which allowed us to sell products under the Ziploc® trademark for 90 days after the end of the Agreement. Our exit of the Ziploc® product line is considered a strategic shift and will have a major effect on our operations and financial results on a go forward basis therefore, this product line has been presented as discontinued operations and was abandoned as of March 31, 2020. The Ziploc® product line recorded losses from discontinued operations, net of taxes of ($ 2,024,851 1,111,452 In October 2021, the Company sold its interest in Flexo Universal (its subsidiary in Mexico that manufactured latex balloons). This transaction was recorded during the fourth quarter of 2021. The Company recorded an expense of approximately $ 10 6 245,000 500,000 255,000

Subsequent Events [Abstract]
Subsequent Events	20. Subsequent Events During May 2022 the Company received a notice of deficiency from the NASDAQ related to a failure to maintain a $1 bid price during a 30 day period. The Company had to achieve a $1 bid price for no fewer than ten (10) consecutive trading days during a 180 day grace period in order to regain compliance. During November, 2022, the Company had not regained compliance with the minimum bid price requirement which caused the NASDAQ to send the Company a delisting letter, subject to appeal. The Company filed a timely appeal, which was heard by a Hearing Panel on January 5, 2023. Consistent with the outcome of that Hearing, and in light of the recovery in the Company’s bid price, on January 19, 2023, the NASDAQ informed the Company that it had regained compliance with this standard. During January 2023, approximately $ 0.8 0.6 During February 2023, the investor of Series B preferred converted into approximately 1.9

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Yunhong CTI Ltd., its wholly owned subsidiary CTI Supply, Inc. and former wholly owned subsidiary CTI Balloon Ltd and its former majority owned subsidiaries, Flexo Universal and CTI Europe. All significant intercompany accounts and transactions have been eliminated upon consolidation. As discussed in Note 21 Discontinued Operations, effective in 2019, the Company determined that it was exiting CTI Balloons Limited and CTI Europe, and during 2021 sold its interest in Flexo Universal. Accordingly, the operations of these entities are classified as discontinued operations in these financial statements.
Variable Interest Entities	Variable Interest Entities The determination of whether or not to consolidate a variable interest entity under U.S. GAAP requires a significant amount of judgment concerning the degree of control over an entity by its holders of variable interest. To make these judgments, management has conducted an analysis of the relationship of the holders of variable interest to each other, the design of the entity, the expected operations of the entity, which holder of variable interests is most “closely associated” to the entity and which holder of variable interests is the primary beneficiary required to consolidate the entity. Upon the occurrence of certain events, management reviews and reconsiders its previous conclusion regarding the status of an entity as a variable interest entity.
Foreign Currency Translation	Foreign Currency Translation The financial statements of foreign subsidiaries were translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities, the historical exchange rate for stockholders’ equity, and a weighted average exchange rate for each period for revenues and expenses. Translation adjustments were recorded in accumulated other comprehensive income (loss) as the local currencies of the subsidiaries are the functional currencies. Foreign currency transaction gains and losses were recognized in the period incurred and are included in the consolidated statements of operations. This issue became moot with the elimination of all foreign subsidiaries between 2019-2021.
Use of Estimates	Use of Estimates In preparing financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the amounts reported of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period in the financial statements and accompanying notes. Actual results may differ from those estimates. The Company’s significant estimates include valuation allowances for doubtful accounts, inventory valuation, deferred tax assets, goodwill and intangible asset valuation, leasehold assets and liabilities, Preferred Stock deemed dividends and beneficial conversion feature values, and assumptions used as inputs in the Black-Scholes option-pricing model.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits and short-term investments with original maturities of three months or less.
Accounts Receivable	Accounts Receivable Trade receivables are carried at original invoice amount less an estimate for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by identifying troubled accounts, evaluating the individual customer receivables through consideration of the customer’s financial condition, credit history and current economic conditions and use of historical experience applied to an aging of accounts. A trade receivable is considered to be past due if any portion of the receivable balance is outstanding for a period over the customer’s normal terms. Trade receivables are written off when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using standard costs which approximates costing determined on a first-in, first-out basis, to reflect the actual cost of production of inventories. Production costs of work in process and finished goods include material, labor and overhead. Inventory is not recorded in excess of net realizable value.
Property, Plant and Equipment	Property, Plant and Equipment Property and equipment are stated at cost. Expenditures for maintenance and repairs are charged to operations as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are amortized on a straight-line method over the lesser of the estimated useful life or the lease term. The estimated useful lives range as follows: Schedule of Property Plant and Equipment (in years) Building 25 30 Machinery and equipment 3 15 Projects that prolong the life and increase efficiency of machinery 3 5 Light Machinery 5 10 Heavy Machinery 10 15 Office furniture and equipment 5 8 Intellectual Property 9 15 Leasehold improvements 5 8 Furniture and equipment at customer locations 1 3 Light machinery consists of forklifts, scissor lifts, and other warehouse machinery. Heavy machinery consists of production equipment including laminating, printing and converting equipment. Projects in process represent those costs capitalized in connection with construction of new assets and/or improvements to existing assets including a factor for interest on funds committed to projects in process of $ 108,000 220,000
Stock-Based Compensation	Stock-Based Compensation The Company has stock-based incentive plans which may grant stock option, restricted stock and unrestricted stock awards. The Company recognizes stock-based compensation expense based on the grant date fair value of the award and the related vesting terms. The fair value of stock-based awards is determined using the Black-Scholes model, which incorporates assumptions regarding the risk-free interest rate, expected volatility, expected option life, and dividend yield. See Note 14 for additional information.
Fair Value Measurements	Fair Value Measurements Current professional accounting guidance applies to all assets and liabilities that are being measured and reported on a fair value basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market. The requirements prescribe a fair value hierarchy that has three levels of inputs, both observable and unobservable, with use of the lowest possible level of input to determine fair value. A Level 1 input includes a quoted market price in an active market or the price of an identical asset or liability. Level 2 inputs are market data other than Level 1 inputs that are observable either directly or indirectly including quoted market prices for similar assets or liabilities, quoted market prices in an inactive market, and other observable information that can be corroborated by market data. Level 3 inputs are unobservable and corroborated by little or no market data. The carrying value amounts of the Company’s cash and cash equivalents, accounts and notes receivable, accounts payable and other current liabilities are reasonable estimates of their fair values due to the short-term nature of these instruments. The fair value of business segments (as needed for purposes of determining indications of impairment to the carrying value of goodwill) is determined using an average of valuations based on market multiples and discounted cash flows, and consideration of our market capitalization. See Note 5 for further discussion.
Valuation of Long Lived Assets	Valuation of Long Lived Assets The Company evaluates whether events or circumstances have occurred which indicate that the carrying amounts of long-lived assets (principally property, plant and equipment) may be impaired or not recoverable. The significant factors that are considered that could trigger an impairment review include: changes in business strategy, market conditions, or the manner of use of an asset; underperformance relative to historical or expected future operating results; and negative industry or economic trends. In evaluating an asset for possible impairment, management estimates that asset’s future undiscounted cash flows and appraised values to measure whether the asset is recoverable. The Company measures the impairment based on the projected discounted cash flows of the asset over its remaining life.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs are amortized over the term of the loan. Upon a refinancing, existing unamortized deferred financing costs are expensed.
Income Taxes	Income Taxes The Company accounts for income taxes using the liability method. As such, deferred income taxes reflect the net tax effects of temporary differences between carrying amounts of assets and liabilities for financial reporting purposes and the amount used for income tax purposes. Realization of deferred tax assets is dependent upon future earnings, the timing and amount of which are uncertain. Deferred tax assets and liabilities are measured using enacted tax rates expected to be in effect when the anticipated reversal of these differences is scheduled to occur. Deferred tax assets are reduced by a valuation allowance when management cannot determine, in its opinion, that it is more likely than not that the Company will recover that recorded value of the deferred tax asset. The Company is subject to U.S. Federal, state and local taxes as well as foreign taxes in Mexico (through October 2021). U.S. income tax expense and foreign withholding taxes are provided on remittances of foreign earnings and on unremitted foreign earnings that are not indefinitely reinvested. We utilize a two step approach to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not the position will be sustained upon tax authority examination, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. See Note 10 for further discussion.
Revenue Recognition	Revenue Recognition On January 1, 2018, we adopted Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers Net sales include revenues from sales of products and shipping and handling charges, net of estimates for product returns. Revenue is measured at the amount of consideration the Company expects to receive in exchange for the transferred products. Revenue is recognized at the point in time when we transfer the promised products to the customer and the customer obtains control over the products. The Company recognizes revenue for shipping and handling charges at the time the goods are shipped to the customer, and the costs of outbound freight are included in cost of sales, as we have elected the practical expedient included in ASC 606. In most cases, the Company has a single product delivery performance obligation. Accrued product returns are estimated based on historical data and evaluation of current information. The Company provides for product returns based on historical return rates. While we incur costs for sales commissions to our sales employees and outside agents, we recognize commission costs concurrent with the related revenue, as the amortization period is less than one year and we have elected the practical expedient included in ASC 606. We do not incur incremental costs to obtain contracts with our customers. Our product warranties are assurance-type warranties, which promise the customer that the products are as specified in the contract. Therefore, the product warranties are not a separate performance obligation and are accounted for as described herein. Sales taxes assessed by governmental authorities are accounted for on a net basis and are excluded from net sales. A disaggregation of product net sales is presented in Note 16.
Research and Development	Research and Development The Company conducts product development and research activities which include (i) creative product development and (ii) engineering. During the years ended December 31, 2022 and 2021, research and development activities totaled approximately $ 200,000 206,000
Advertising Costs	Advertising Costs The Company expenses advertising costs as incurred.

Subsequent Event [Line Items]
Notice deficiency description		During May 2022 the Company received a notice of deficiency from the NASDAQ related to a failure to maintain a $1 bid price during a 30 day period. The Company had to achieve a $1 bid price for no fewer than ten (10) consecutive trading days during a 180 day grace period in order to regain compliance. During November, 2022, the Company had not regained compliance with the minimum bid price requirement which caused the NASDAQ to send the Company a delisting letter, subject to appeal. The Company filed a timely appeal, which was heard by a Hearing Panel on January 5, 2023. Consistent with the outcome of that Hearing, and in light of the recovery in the Company’s bid price, on January 19, 2023, the NASDAQ informed the Company that it had regained compliance with this standard.
