The Skipper is an extremely fun and affordable toy that challenges kids to all three of Just Jump It's core design goals - agility balance and coordination. The Skipper features a colorful molded end-ball and the same high quality braided polypropylene line that is the hallmark of the Just Jump It product line. Simply slip the loop over your ankle swing the ball and jump over it with the opposite foot. The ball will not come off and the loop is steadfast. For ages 6 and up.
