Thank you very much for your many follows and repeat purchases. In the unlikely event that you are not satisfied, we will accept returns and exchanges within 30 days of product arrival. 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. Please take advantage of this opportunity. These are balls that were opened in early February and used for about 3 weeks in practice for women's training with a hard coat. They are generally scuffed, but the air pressure is still good, so they are recommended for対人練習 (sparring/partner practice). We will check the air pressure before packing, so please use them with confidence. We will respond immediately even if you purchase without prior notice. 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. In the unlikely event that you wish to return the item, please contact us before leaving a review.
