Thank you very much for your follows and repeat purchases. In the unlikely event that you are not satisfied, we offer a refund or exchange within 30 days of receiving the product, even for your convenience. We hope you can purchase with peace of mind. Since items sell out quickly, we are unable to offer discounts. We appreciate your understanding. As a first-time purchase bonus, we are offering an additional ball service. We also have repeat purchase benefits. Please take advantage of this opportunity. These balls were opened in early December and used for only one 3-set match on a carpet court. The felt is in relatively good condition as shown in the images. The air pressure is also good, so they are recommended for practice with others, service practice, and drills that use a lot of balls. We believe these balls can be used by a wide range of people, from children and women to adults, and from beginners to advanced players. We will respond immediately to immediate purchases. We have about 200 balls in stock. If you purchase a large quantity, we will offer a significant discount, so please contact us before purchasing.
