Step 3: Sample Confirmation (If Required)

For first-time cooperation or customized products, we offer sample testing to ensure product suitability:

- Sample production time: 3–7 working days (depending on complexity)

- Sample delivery: International express (DHL/FedEx/UPS, shipping cost borne by buyer)

- Confirmation: After you verify sample performance, appearance, and quality, we proceed to the formal order.
