Holiday Notice

Since China’s National Day is approaching, we’d like to inform you that we’ll have a seven-day holiday from Oct. 1st to Oct. 7th (GMT+8) during which your question or email may not be replied immediately. However, quotation or orders can be submitted online as usual.

In order not to get your manufacturing efficiency reduced, we strongly suggest you submit quotation or order in advance so that manufacturing can be done or started at least before our public holiday. We’ll be back at your service on Oct 8th.
