Due to the alternating textures, this is an excellent hand held chewable fidget for children seeking sensory input. The alternating textures were designed by therapists to also simulate a variety of food textures, therefore assisting those who have sensory issues when certain textures are placed in their mouth. Easy to grasp and hold onto OR to slip a retractable keychain or lanyard onto. This red one has no flavour. Made from FDA approved materials, and extremely durable but should be used under supervision.
