Jelly Blox - the only blocks that bend the rules! Jelly Blox is a patent-pending building system for toddlers & preschoolers that kids can squeeze, stretch, and squish! Designed to support key developmental milestones through the fun of tactile, sensory play, Jelly Blox delivers jiggly construction fun. A few special blocks are also filled with fun sensory fills like sand, foam balls, mini stars, and mini bricks to dial up the fun! Oh, and a bonus for parents - not only are Jelly Blox safety tested to ensure worry-free play, but they’re also totally ouch-free; no need to dread those accidental encounters with bare feet!
