The green knobby Chewy Tube is great for the kids that like a more tactile chewy tube. It is about the same size as the 1R Red Chewy Tube, but with bumps on it. These are great for a jaw assessment program or just for a child that needs to chew the heck out of something. Not for children under 9 months old. Use with adult supervision.
