The Vollint Mini Orange are Stage 2 tennis balls designed for learning the game and developing correct stroke technique. They have 50% less pressure than standard tennis balls to provide slower speed and lower, predictable bounce to give players more time to hit the ball. With a quality, two-tone acrylic felt, the balls ensure added durability and allow for keeping track of spin development. They are perfect for training and can be used on a 60-foot court. The balls are suitable for beach tennis and come in a practical mesh bag for easy transportation. They are ideal for adult beginners and juniors aged 10 and under. The Mini Orange balls are supplied in a 5-dozen pack (60 balls).
