These balls were used for practice, etc., on an omni court for about 3 months. There are 94 balls. Please judge the condition from the actual product photos. There are many, so I think you can use them for serve practice, ball feeding practice, etc. Also, I think they can be used for baseball toss batting, etc. HEAD PRO balls are high-quality practice balls that, in particular, suppress air leakage by about 33%, enabling stable bounce and control for a long time. 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 are match balls that can of course be used in international tournaments. Although they are positioned as practice balls in Japan because they are not JTA official, their high grade has been proven. Usage: Hard court Type: Pressure ball
