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. As a first-time 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 January and used for a week of women's practice on a hard court. The felt has some scuffing as shown in the images. Also, the air pressure has decreased somewhat, but they are recommended for practice sessions or for practices using many balls. We believe these balls can be used by a wide range of people, from children and women to adults, and from beginners to intermediate players. We will respond immediately to instant 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♪
