The CHUIT Tetra Fidget Chew packs a lot of features into one cool chew tool. With 4 differently textured extensions to chew on, you'll never get bored! Rotate between circular bumps, zigzag bumps, ribs, and lines - a sensory seeker's dream. Each extension is long enough to reach the back molars for proprioceptive input to the jaw and masseter muscle.Not just a chew, the Tetra Fidget Chew also makes a great hand fidget! Put your pointer finger inside the hole and use your other hand to make it spin on your finger. Or, hold it in both hands by the circular extensions and twist to make it spin. It's great for increasing focus and practising fine motor skills and hand-eye coordination.
