The Penn QST 36' Felt Ball is perfect for a 10 and under player playing on a 36' tennis court. The felt balls feature a denser core, which allow for younger players to keep up with the pace of the game. The Penn QST 36' Ball fits USTA standards for a 36' tennis court, but can also be used for training with adults and bigger kids. The mesh bag contains 12 balls covered in yellow and orange felt.
