Thank you very much 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 for reasons of customer 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 initial bonus, we are offering an additional ball service. We also have repeat customer benefits. We hope you will take advantage of this opportunity. These are balls that were opened in early March and used for about 3 days on an omni court by women. The felt is in beautiful condition as shown in the images. We will ensure the air pressure is maintained, making them ideal for various practice types, including practice against opponents and rally practice. We believe they can be widely used by children, women, and adults, as well as by beginners and advanced players. They have the club logo as they were purchased from a tennis club. We will respond promptly even if you purchase immediately. We have approximately 200 balls in stock. If you purchase a large quantity, we will offer a significant discount, so please contact us before purchasing ♪
