Thank you very much for your follows and repeat purchases. If you are not satisfied, we offer a refund or exchange within 30 days of receiving the product, even if it's due to the customer's circumstances. We hope you can purchase with peace of mind. Due to the items selling out quickly, we are unable to offer discounts. We appreciate your understanding. As a first-time purchase bonus, we are offering an additional ball service. Please take advantage of this opportunity. These balls were opened in early November and used for about a week on an omni court for women's practice. The felt is in very good condition. The air pressure decreases over time, so they are ideal for repetitive practice using many balls, service practice, and practice for women and children. They are also used for baseball batting practice. The manufacturers are mixed. We will respond immediately to immediate 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♪
