For products with optional sizes, we will attach an accurate size chart for you to choose and buy. The following product details are some instructions on the condition of the product, which can answer some of your questions and improve your shopping experience. Due to different shipping batches, there may be subtle differences in the outer packaging of some products. We will provide users with beautiful and high-quality outer packaging without affecting product quality. Due to the layout of the product page, the SKU pictures in some products may show multiple products of the same style or SKU pictures that are different from the specification description. SKU pictures are for reference only. If the specification description is not clearly stated, the quantity of goods in the specification is one piece. If the SKU picture does not match the product specification description, the product description shall prevail. If you have any relevant questions, you can contact us by email, and we will solve your concerns quickly and accurately. [Product Testing]: Before shipping and packaging, our company will also test each item to ensure that you receive the product smoothly. If you have any questions, please communicate with us by email, and we will reply to your questions ASAP to ensure that the problem is solved and avoid any unpleasant incidents.
