| Accounting Policies [Abstract] | |
| Consolidation, Policy [Policy Text Block] | Principles of consolidation |
|
| The consolidated financial statements, prepared in accordance with generally accepted accounting principles in the United States of America (“US GAAP”), include the assets, liabilities, revenues, expenses and cash flows of all subsidiaries. All significant intercompany balances, transactions and cash flows are eliminated on consolidation. |
| | | |
| Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign currency translation |
|
| The functional currency of the Company is United States Dollar. The functional currency of the subsidiaries other than the subsidiaries in the PRC and the Thailand is Hong Kong dollar. The subsidiaries in the PRC and Thailand have their local currency, Renminbi, Thai Baht as their functional currencies. |
|
| In the individual financial statements of the consolidated entities, foreign currency transactions are translated into the functional currency of the individual entity using the exchange rates prevailing at the dates of the transactions. At the reporting date, monetary assets and liabilities denominated in foreign currencies are translated at the foreign exchange rates ruling at the reporting date. Foreign exchange gains and losses resulting from the settlement of such transactions and from the reporting date retranslation of monetary assets and liabilities are recognized in the consolidated statement of income. Aggregate net foreign currency transaction gain (loss) were HK$10,127, HK$2,102, (HK$8,206) and (HK$5,223) for the year ended April 30, 2012, the 8-month period ended December 31, 2012 and for the years ended December 31, 2013 and 2014, respectively. |
|
| Non-monetary items carried at fair value that are denominated in foreign currencies are retranslated at the rates prevailing on the date when the fair value was determined and are reported as part of the fair value gain or loss. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated. |
|
| In the consolidated financial statements, all individual financial statements originally presented in a currency different from the Company’s reporting currency have been converted into Hong Kong dollars. Assets and liabilities have been translated into Hong Kong dollars at the closing rates at the reporting date. Income and expenses have been converted into the Hong Kong dollars at the exchange rates ruling at the transaction dates, or at the average rates over the reporting period provided that the exchange rates do not fluctuate significantly. Any differences arising from this procedure have been recognized in other comprehensive income and accumulated separately in the shareholders’ equity. |

| Use of Estimates, Policy [Policy Text Block] | Use of estimates |
|
| The preparation of consolidated financial statements in conformity with the US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The most significant estimates relate to allowances for doubtful accounts, inventory valuation, useful lives of property, plant and equipment, valuation allowance for deferred tax assets and contingencies. Actual results could differ from those estimates made by management. |

| | | |
| Property, Plant and Equipment, Policy [Policy Text Block] | Property, plant and equipment |
|
| Property, plant and equipment, other than construction in progress, are stated at acquisition cost less accumulated depreciation and impairment losses. The cost of an asset comprises its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use. |
|
| Depreciation is provided to write off the cost less their residual values over their estimated useful lives, using the straight-line method, at the following rates per annum: |
|
| Buildings | | 4%-5% | |

|
| The assets’ estimated residual values, depreciation methods and estimated useful lives are reviewed, and adjusted if appropriate, at each reporting date. |
|
| Construction in progress represents assets in the course of construction for production or for its own use purpose. It is stated at cost less any impairment loss and is not depreciated. Cost includes direct costs incurred during the periods on construction, installation and testing plus interest charges arising from borrowings used to finance these assets during the construction period, if any. Construction in progress is reclassified to the appropriate category of property, plant and equipment and depreciation commences when the construction work is completed and the asset is ready for use. |
|
| The gain or loss arising on retirement or disposal is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in the consolidated statement of income. |
|
| All other costs, such as repairs and maintenance are charged to the operations during the financial period in which they are incurred. |
| | | |
| Prepaid Lease Payments and Lease Financing, Policy [Policy Text Block] | Prepaid lease payments |
|
| Upfront payments made to acquire land held under an operating lease are stated at costs less accumulated amortization and any accumulated impairment losses. The determination if an arrangement is or contains a lease and the lease is an operating lease is detailed as below. Amortization is calculated on a straight line basis over the term of the lease/right of use except where an alternative basis is more representative of the time pattern of benefits to be derived by the Company from use of the land. |
| | | |
| Lease, Policy [Policy Text Block] | Leases |
|
| Leases are classified at the inception date as either a capital lease or an operating lease. For the lessee, a lease is a capital lease if any of the following conditions exist: a) ownership is transferred to the lessee by the end of the lease term, b) there is a bargain purchase option, c) the lease term is at least 75% of the property’s estimated remaining economic life or d) the present value of the minimum lease payments at the beginning of the lease term is 90% or more of the fair value of the leased property to the lessor at the inception date. A capital lease is accounted for as if there was an acquisition of an asset and an incurrence of an obligation at the inception of the lease. All other leases are accounted for as operating leases. The Company has both capital leases and operating leases in the periods presented. |
| | | |
| Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Valuation of long-lived assets |
|
| The Company periodically evaluates the carrying value of long-lived assets to be held and used when events and circumstances warrant such a review. The carrying value of a long-lived asset is considered impaired when the anticipated undiscounted cash flow from such asset is separately identifiable and is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset. Fair market value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved. Losses on long-lived assets to be disposed of are determined in a similar manner, except that fair market values are reduced for the cost to dispose. |
| | | |
| Revenue Recognition, Policy [Policy Text Block] | Revenue recognition |
|
| Sales of goods are recognized when goods are shipped, title of goods sold has passed to the purchaser, the price is fixed or determinable as stated on the sales contract, and its collectability is reasonably assured.

| Income Tax, Policy [Policy Text Block] | Income taxes |
|
| The Company accounts for income taxes in accordance with FASB ASC 740 “Income taxes”, which requires an entity to recognize deferred tax assets and liabilities using the asset and liability method. Under this method, deferred income taxes are recognized for all temporary differences at enacted rates and classified as current or non-current based upon the classification of the related asset or liability in the consolidated financial statements. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some portion of, or all, the deferred tax asset will not be realized. |
|
| FASB ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements, and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides accounting guidance on de-recognition, classification, interest or penalties, accounting in interim periods, disclosure and transition.

| | | |
| Earnings Per Share, Policy [Policy Text Block] | Net income per share |
|
| Basic net income per share is computed by dividing net income available to ordinary shares by the weighted average number of ordinary shares outstanding during the period. Diluted net income per share gives effect to all dilutive potential ordinary shares outstanding during the period. The weighted average number of ordinary shares outstanding is adjusted to include the number of additional ordinary shares that would have been outstanding if the dilutive potential ordinary shares had been issued. In computing the dilutive effect of potential ordinary shares, the average stock price for the period is used in determining the number of treasury shares assumed to be purchased with the proceeds from the exercise of derivative securities. |
| | | |
| Derivatives, Policy [Policy Text Block] | Derivatives |
|
| Derivatives are carried at fair value and are reported as other current assets when the Company has a contractual right to receive cash from the counterparty that are potentially favorable to the Company and as accrued and other current liabilities where the Company has a contractual obligation to deliver cash to a counterparty that are potentially unfavorable to the Company. |
|
| If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and the hedged item are recognized in the consolidated statement of income and comprehensive income. If the derivative is designated as a cash flow hedge, changes in the fair value of the derivative are recorded in other comprehensive income and are recognized in the consolidated statement of income and comprehensive income when the hedged item affects net income. If a derivative does not qualify as a hedge, it is marked to fair value through the consolidated statement of income and comprehensive income. |
| | | |
| Fair Value Measurement, Policy [Policy Text Block] | Fair Value Measurements |
|
| The Company has adopted FASB ASC 820 “Fair Value Measurements and Disclosures” which defines fair value, establishes a framework for measuring fair value in the US GAAP, and expands disclosures about fair value measurements. It does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. |
|
| Its establishes a three-level valuation hierarchy of valuation techniques based on observable and unobservable inputs, which may be used to measure fair value and include the following: |
|
| Level 1 - | Quoted prices in active markets for identical assets or liabilities. | |
|
| Level 2 - | Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. | |
|
| Level 3 - | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. | |
|
| Classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. |
| | | |
| New Accounting Pronouncements, Policy [Policy Text Block] | Recently issued accounting pronouncements |
|
| In May 2014, the FASB issued ASU 2014-9, “Revenue from Contracts with Customers”, (ASU 2014-09), which create a new Topic, Accounting Standards Codification Topic 606. The standard is principle based and provides a five-step model to determine when and how revenue is recognized. AUS 2014-09 requires entities to recognize revenue to depict the transfer of promised goods or services to customers in amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 requires entities to disclose both qualitative and quantitative information that enables users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers, including disclosure of significant judgements effecting the recognition of revenue. The accounting standard is effective for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted. The Company is currently evaluating the impact of adopting this guidance. |
|
| In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which defines management’s responsibility to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures if there is substantial doubt about its ability to continue as a going concern. The pronouncement is effective for annual report beginnings ending after December 15, 2016 with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements. |
