2. Each product will be inspected before shipment! However, it is inevitable that the product will still produce bad situations when it comes to customers. Factory quality problems, we promise: can be returned or exchanged. Our profit has been controlled very low, mainly by running volume, and we can't afford the postage back and forth (this is not Taobao). If you encounter something bad, please keep it properly and return it to us after accumulating the quantity. Regarding the issue of return and exchange postage, we will bear it within 7 days. If the postage exceeds 7 days, we will pay each other. The return postage standard will be charged according to your standard. (if you place an order, you will be deemed to agree) not according to the standard you pay for express delivery!! For cooperating customers, we shall bear the postage during the cooperation period (basically there are purchases every month).
