As a wholesale industry, with low prices and large shipment volumes, there is inevitably a possibility of quality issues or defects. If you find damaged, quality problems or defects with the goods after receiving them, please accumulate a certain quantity before exchanging (more than 10 pieces) or exchange them next time. We will cover the return shipping cost (domestic only). If you want to exchange the goods immediately, the buyer will bear the round-trip shipping costs. For detailed information, please refer to the wholesale rules of our store. Place orders based on the rules. If you are not clear, you can consult Wangwang. Only place orders after understanding. Thank you for your cooperation. Wish you a prosperous business!
