The Rainbow Mega Bounce Ball features a dimpled, textured surface that just wants to be picked up and played with! It can be thrown and bounced too - the dimpled surface could cause the ball to hop and deflect - which way will it go? Great for children and adults who love to fiddle and fidget. It can help to alleviate stress too. The Mega Bounce Ball is ideal for those who respond to sensory, tactile, and visual stimulation. It can help to develop fine motor skills, gross motor skills, and hand-eye coordination.
