1. Made of solid, durable, high-density rubber for superlative bounce and carom. 2. A fresh, fun way to supercharge reflexes and agility for faster hands and better footwork. 3. Six rounded knobs create totally unpredictable, random bounces, pops and leaps. 4. Random bounces train hand-eye coordination, cut reaction times and improve visual tracking. 5. Great for all hard surfaces: wood, asphalt, clay, even dirt.
