1. Color difference issue: All products are photographed in real life, trying to make the colors look as close to the actual product as possible. Customers who cannot tolerate any color difference should be cautious to avoid unnecessary waste of money and time. 2. Size issue: Please read the product description carefully before purchasing or communicate with us first. When buying, please specify the color and size of the product you want; otherwise, we will default to shipping according to the title description. 3. Quality issues: We will try our best to disassemble and thoroughly check items before shipping. Size and color issues are not caused by our negligence in shipping. If you need to exchange, the shipping cost will be borne by the buyer. If you indeed find quality issues after receiving the goods, please contact us within 48 hours of receipt and provide relevant photo evidence. We will definitely resolve it properly for you, and we will cover the postage. Please check carefully before use as each customer's requirements are different, making it impossible to achieve perfection in the eyes of every customer. Please don't worry too much about some minor flaws that do not affect wear and use at all.
