Chewable shapes used to offset a sensory seeking childs need to chew or grind. This product is compact enough to be carried in the pocket and comes in fun shapes as to not draw embarrasing attention to the child using it. We have had hundreds of kids want to collect these after seeing others with them. This incentive makes the user not feel as if he or she must hide the product. Each product comes with an official letter signed by a licenced OT stating that this product is an oral motor device and not a toy therefore making it allowable at school. Ages 3 and up.
