Gryphon's junior minkey balls are 70% of the weight of a regular adult match ball, making them an ideal training and learning ball for junior players and those new to the sport. The Minkey Ball also has a slightly rubberized coating, which helps rapidly develop basic skills. Recommended for players U6 to U13, or new players. The Minkey Ball comes in a variety of fun, bright colours, so you won't lose it in the backyard or wherever you happen to be training next!
