Chewy Tubes are an innovative oral-motor device designed to provide a resilient, non-edible, chewable surface for practicing biting and chewing skills. They provide great oral proprioceptive input especially for those who demonstrate teeth grinding and mouthing of non-food objects. The Yellow Chewy Tube has the narrowest bitable stem (3/8" outside diameter) of all the Chewy Tubes. Chewy Tubes are non-toxic, latex free, non-flavored and compliant with FDA standards. To top it all off, they're bendable and provide an excellent outlet for those with fidgety fingers.
