3. Q: Can you provide a sample? Are these samples free?
A: Yes, we provide 5-10 pcs of connector free samples for testing. But you have to pay for the shipping cost
4. Q: What about your delivery time?
A: Stock goods are delivered within 1 day; customized goods are delivered within 5-7days
5. Q: How to ship my order?
A: For small packages, send them by Express, such as DHL, FedEx, UPS, TNT, EMS. That's Door-to-Door service. For big packages, we can send them by Air or by sea. We use standard export cartons. We are responsible for any product damage caused during delivery.
