ARK's Basketball Chew Necklace is a sensory slam dunk! This rounded disc pendant measures about 1.75" in diameter and half an inch at the thickest part (in the center of the pendant) - perfect for those who prefer chewing with their pre-molars and/or front teeth. Use this oral sensory solution as a safe alternative to chewing on pencils, shirts, fingers, etc. and to help calm, focus, and self-regulate.
