The Head TIP Foam Mini tennis balls are designed for pleasant playing and learning experience and are suitable for kids aged 5-8. These non-pressurized are designed as a part of the Head’s Tennis Instruction Program in cooperation with International Tennis Federation and its "Tennis Play and Stay!" campaign. The balls offer great bounce, better responsiveness and optimal durability, and they are suitable for ITF’s small red court. Furthermore, the two-tone yellow and red felt balls provide increased visibility, and the softer and much slower motion ensures comfortable practice for the children. The balls are shipped in bulk as a dozen.
