Bounce these Sensory Flashing Balls and watch them light up. But watch out. Their uneven surfaces make them bounce and hop in different directions. These multi-sensory balls have bright, flashing LED lights inside of them. The lights and the textures work together to endlessly fascinate children. Made of durable rubber without seams or holes, this 4-piece set is suitable for ages 3+. The set includes balls in blue, pink, yellow and green. Size: 3.1" dia.
