ITF Approved HEAD PRO Hard Tennis Balls These balls were used for practice, etc. on an Omni court for about 3 months. *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 116 balls, so you can use them for serve practice, ball feeding practice, etc. You can also use them for baseball toss batting practice. HEAD PRO balls are high-quality practice balls that allow for long-lasting stable bounce and control, especially by suppressing air leakage by about 33%. High-quality materials are also used for the felt, achieving both 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 as match balls in international tournaments. In Japan, they are positioned as practice balls because they are not JTA official, but their high grade has been proven. Usage: Hard court Type: Pressure ball
