ARK's Tetra-Bite® 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-Bite also makes a great hand fidget tool! 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 practicing fine motor skills and hand-eye coordination.
Toughness Guide: Standard - This is the softest level, recommended for mild chewers (those who do not chew through anything).XT / Medium Firm - This is the middle level. It's firmer, but still fairly chewy, recommended for moderate chewers. XXT / Very Firm - This is the toughest level. It still has some “chewability” to it, but it’s fairly rigid / pretty firm. No chew tool is indestructible, but this is usually the longest lasting level for avid chewers.
