1. Please make sure to fill in your detailed shipping address and contact information (preferably a mobile phone number). The goods will be shipped based on the information you provide, so please ensure that your phone is always on.

2. Online sales cannot avoid color differences: Under different colors of light and on different monitors, the appearance of the product can cause color difference issues. Therefore, those who cannot accept any color differences are requested to carefully check before purchasing. Color difference issues will not be used as the basis for negative feedback, complaints, and returns and exchanges.

3. All goods sold will undergo quality and quantity checks before shipment. If you receive a damaged, incorrect quantity, or overflowed product, please refuse to accept the delivery first, and then contact the shop owner in time. When receiving the goods, please carefully inspect to ensure there are no problems, and then sign for receipt. If you want to have your colleague or the gatekeeper sign for you, make sure to communicate this in advance. Once the receipt is signed, it represents that you have acknowledged it.

4. Your every evaluation is the cornerstone of our company's growth. If you have any dissatisfaction, please communicate with our customer service first, and we will properly resolve it. Because the ultimate satisfaction and happy cooperation with you are the most important.

5. For multiple purchases, only one shipping fee is charged, and it's more cost-effective to send multiple items together. Please plan your orders carefully, and if you want to buy multiple items, please use the shopping cart.

6. How to use the shopping cart: Click on the model options next to the main image of the product (since these products are listed by model, so the color is selected there), and the corresponding price will appear. Enter the number of needed pieces, click 'Add to Cart', continue to select, and when all are selected, go to the shopping cart. Click the bottom right 'Quick Purchase' to successfully purchase all in one go, which is convenient and fast. The system will calculate the shipping fee.
