Moluk Building Genius is a unique 9-piece set that includes three of your favorite Moluk toys: the Hix, Mox, and Oibo. The Hix are three silicone rubber cones that can fold, flip, and stack endlessly. The Mox are right-side, inside-outside face-making rubber balls. The Oibo are a set of elastic, stackable, rollable, squeezable, easy-to-grip sensory cubes. Separately, they're each an award-winning sensory experience designed to invite open-ended exploration at varying levels of development. Together, they take play to the next level! Watch as they help your child grow, surprising you and your little one with new uses and new challenges along the way - from grasp & sense to stack & build to imagine & invent! Meanwhile, every single part of this set is made entirely of soft silicone - so you know it's safe for the littlest explorers.
