Company Policy: Strive for the Customer Satisfaction

We have rich experience upon the international order all over the world. We can deliver the order to APO Box. We will combine the shipping cost for multi items purchase. 


Before Shipping

We will deliver the item to the customer in one or two business handling day when the payment is cleared. We will check the order carefully before it is sent to you.

We will pack the order well tough with normal appearance, which is easy for your custom clearance. If you need additional request upon the packing please let us informed at the first time.


If possible, please supply us with your telephone number only for the purpose of your local post office needs. In case that you are absent and not able to pick up the item at your location in time, the post office may call you for reminder (Mostly, mail carrier will only put a notice).

P.S: We keep high security and confidentiality for our customers personnel information.


Shipping Mode

We mainly use EMS and Air Register Mail for worldwide shipping. They are operated by the post office all over the world. EMS Express can be tracked on EMS website (China Post Office) and your local post office. Air Register Mail can be tracked by your local post office. Both need your signature to accept.

If you need the track number, please send an e-mail or leave a message to us for acquisition.


We can also use other express shipping, such as: UPS, DHL, FedEx and TNT etc, while the cost will be higher. You shall contact us first if you need mentioned above service.


Shipping insurance is optional and it is up to the customer.


If you need to know the detailed shipping cost, please send us message.


Shipping Period

Generally speaking, Chinese EMS Express takes about 2 to 4 days from China to Asia countries, about 3 to 6 days to Australia, USA or Canada, about 5 to 10 days to Euro continent and about 6-12 days to South America etc. Be noticed that some countries or places may take longer time.

The shipping period may happen to some exception because of the custom check and post office neglect. You can contact us if you dont have it in regular days. We will firstly check it with track number. If it doesnt work we will send the track application in paper to the post office, which will take several days to acquire the reply. That is the normal track progress set by the Chinese Post Office.


Compared with Hong Kong Post Service, Chinese Chinese Air Register Mail which is cheaper and slower than EMS Express is strange for the shipping period and delivery (mainly because of the international flight). Sometimes fast in 7 days, and sometimes later than 21 days. Moreover it has little and poor information about the shipping condition. We have many cases that even customer gets the item, the system of the post office still tells that it was just sent from China several days ago. In that case, we sincerely hope customers can keep a little more patience for the potential delay, since we cant control the shipping speed of post office and custom release. Many thanks in advance.


Payment Method

We can also accept the payment via Pay-Pal or Western Union or Bank T/T Wire Transaction or Credit Card (in US only) etc.


After Sales Service

Except man-made mistakes, we will exchange the defective with a brand new one within 14 days after you get our product. According to the guild regulations customer shall be responsible for the returning shipping fee.


All scopes and items have three years warranty.

Finally, your feedback and suggestion are very important for us.


Thanks again for your attention. We sincerely hope you will enjoy our products.
