Usually, it is inspected before shipment, and before signing for it, pay attention to checking whether the packaging is intact. If you encounter minor issues such as wire ends, please solve them yourself. For major issues, please contact customer service in a timely manner. Generally, if there is a problem with the bag, we will consider it as scrap after returning it. Please try to negotiate compensation to resolve the issue. If you need to return the goods, due to the low profit margin, the postage for compensating for all wrong shipments and quality issues will be limited to the postage we charged at the time of shipment. Please bear the difference.
