Jellystone Sensory Ball BlueJellystone designs was created by a mum of 3, Claire, in 2016. Jellystone products are created for children who are using all of their senses to explore and make sense of our incredible world. Each product is designed to safely support their exploration and learning; supporting them and calming them when it may seem all too big and overwhelming. The Sensory Ball also caters to older children who can stretch, grasp, roll, squish and bounce it for fun!
