Ideal for learning the sport of tennis and developing correct stroke technique, the Vollint Mini Orange tennis balls are designed for adult beginners and juniors aged 10 and under. They are 50% slower than the standard to allow more time for preparation and offer a lower, predictable bounce. These Stage 2, low-compression balls feature a durable two-tone acrylic felt to guarantee a longer lifespan and enable players to keep track of spin development. They are suitable for training and ensure increased visibility on the court. Also, the Mini Orange balls are great for beach tennis and come in a practical mesh bag with a drawstring. The balls are supplied in a 1-dozen pack.
