Elastic, stackable, rollable, squeezable, easy-to-grip sensory fun for babies and kids of all ages! Oibo merges a sphere with a 3-inch cube, combining the action and fun of a ball with the educational benefits of a building block. They grow with children, too! They're elegant grasping and teething toys for babies, fun bouncing and rolling toys for toddlers, and fun stacking and throwing toys for children. Meanwhile, parents love them because they're wonderfully safe and durable - If you accidentally step on them, they pop right back into shape! Keep the playtime discoveries rolling through the years with the Oibo Sensory Toy.
