 Lead time:
We have a lot of stock ,If the quantity isn't very big , we can send the goods as soon as possible after recieve payment.If big quanity, the lead time need according to the quantity.
Transporting:
If small quantity, usually send by courier (DHL,FEDEX,TNT and so on) . If big quantity, we advice ship by air or by sea. this will use longer time ,but cheaper fees. We are near the port of TianJin.
Our service:
We can offer the sample. If the quality is good, we can offer very very competitive price .And can pack according to customer's requirment.

1. Could I put my own logo on it?

> Sure, of course,we have over 18 years OEM experience,customers' logo can be made by laser, engraved, embossed, transfer printing etc.

2. Should I pay extra for logo printing ?
> If you order amount over out MOQ for OEM package,all OEM fees would be free,if you want to make a trial order,we need to charge a very little fees for the printing and cartons.

3. How about the quality?

> Many of our company's products are sourceed from well-known manufacturers, and the quality is absolutely in line with the corresponding international standards. Some of our company's products are project surplus purchased from telecommunications operators. We guarantee that the products are the original original package. Of course, our company promises to provide a one-year warranty for such products in order to ensure the rights of customers. If there is any quality problem during this period, our company can replace it for free for customers.

4. Could i buy 1pc sample first and small order ?
> Of course, support sample order and small order, especially for new customers under certain condition.

5. How much for 1pc sample ?
> We can provide free samples for some products, but customers need to bear the shipping cost. For some products, we charge a corresponding sample fee.

6. If i have my thoughts, do you have person to design according to my concept?
> Certainly,our design team is willing to do for you.

7. How long to make a sample? 
> 3days which depends on the samples' complexity.
