With elastic geometry the Oibo rolls, stacks, and springs back after every squeeze, inviting playful exploration from the very first months. Oibo dissolves the boundary between ball and building block. It's a square, and it's a circle. Squirkle? For infants, Oibo is a gentle grasping and teething toy. Soft, safe, and easy to hold. As your child grows, it becomes a bouncing ball, a toy for simple throw-and-catch games, something to thread silks through, and a building element that can be stacked, aligned, or nested in countless ways. Oibo’s open structure offers a satisfying tactile response, collapsing under pressure and instantly regaining its shape. Rolling, stacking, and nesting the pieces engage coordination and fine motor skills while giving children an intuitive sense of shape, space, and balance.
