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 if it is due to your convenience. We would be grateful if you could 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 ball service. We also have repeat customer benefits. Please 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 image. We will ensure proper air pressure, making them ideal for various practice sessions, including partner practice and rally practice. We believe they can be widely used by children, women, adults, and from beginners to advanced players. They have the tennis club's 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 ♪
