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 mid-December and used for a week of women's practice on an Omni court. The felt has some wear and tear as shown in the images. The air pressure has decreased somewhat, but they are recommended for service practice and drills where you use a lot of balls. We believe these balls can be used by a wide range of players, 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♪
