A knobby tube is an innovative oral motor tool that is designed to provide a resilient, non-food, chewable surface for children and adults to practice their biting and chewing skills. Designed to bring awareness to the mouth, this device can help develop jaw strength and address sensory issues. The Knobby Tube contains small, round textured bumps on its biteable stem to provide extra oral sensations when placed in the mouth. Intended for individual use with adult supervision, Knobby Tubes are non-toxic, latex and lead free and do not contain PVC or phthalates.
