Inspired by Thor's Hammer, ARK's Hammer chewable pendant necklace is a cool and discreet option for anyone who needs to chew. It's a great option for those who prefer chewing with their pre-molars and/or front teeth. The raised texture provides some extra sensory interest. Use these chewable hammer necklaces as a safe alternative to chewing on pencils, shirts, fingers, etc. and to help calm, focus, and self-regulate.
