ITF Approved HEAD PRO Hard Tennis Balls These balls were used for practice, etc. *The condition may vary slightly depending on the ball, but I think the condition is good as shown in the photos. Please judge the condition from the actual product photos. There are 115 balls, so you can use them for serve practice, ball feeding practice, etc. You can also use them for baseball toss batting, etc. HEAD PRO balls are high-quality practice balls that allow for long-lasting stable bounce and control, especially by reducing air leakage by about 33%. High-quality materials are also used for the felt, achieving durability and the feeling that Japanese players prefer. "HEAD PRO" was used as the official ball at the "China Open 2014" held in Beijing, a WTA Premier tournament (women's). As they are ITF approved balls, they can of course be used in international tournaments. In Japan, they are positioned as practice balls because they are not JTA official, but their high grade has been proven. Uses: Hard court Type: Pressure ball
