Shark Tooth Sensory Chew Necklace - Free Hygiene Case

My grandson chews on things often. He loves this shark tooth for chewing. He thinks its cool to have a shark tooth

I bought this for my grandson. He has been chewing at it and there is not sign of wear as opposed to another one from another store which he has almost chewed through.

Got it for my son who has used it to help with nerves at school. Teacher said it helped him.
