Children of all ages will love to play with light balls that light up and flash when they are bounced. Great for use in open play or in a sensory area. Good too for use in fun games of throw and catch as they are ideal for a young child’s hand. The irregular sensory flashing balls have uneven surfaces which hop and deflect at odd angles when they hit the floor. 4 bright colors: blue, pink, yellow & green. 3.1" diameter.
