Thank you for your many follows and repeat purchases. In the unlikely event that you are not satisfied, we will offer a refund or exchange within 30 days of product arrival, even if it is due to your convenience. We hope you can purchase with peace of mind. As these sell out immediately, we are unable to offer discounts. We appreciate your understanding. As an introductory offer, we are providing an additional service of balls. We also have repeat customer benefits. Please take advantage of this opportunity. These are balls that were opened in early January and used for one week on an omni court by women. The felt is in a state where there is some wear as shown in the image. Also, the air pressure has decreased over time. They are recommended for service practice and practice where many balls are used. We believe they can be widely used by children, women, adults, and from beginners to intermediate players. For protection during shipping, the balls will be packed in a plastic case. Although 50 balls are shown in the photo, we will carefully select and prepare 40 balls. We will respond immediately even if you purchase immediately. 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 ♪
