Suitable for developing on-court skills and gaining more confidence in your game, the Dunlop Stage 1 green mini tennis balls are approximately 25% slower than a standard tennis ball to give you more time to prepare your return shot. These ITF (International Tennis Federation) approved balls are great for coaching and training and have been designed for children aged 9-10. They are ideal as transition balls from Stage 2 to standard tennis balls and come in a pack of 60 (5 dozen).
