VibraZillas feature an easy-to-grip chunky handle, 6 therapeutic speeds, and a 3-1/2″ duo-texture chewy tip that is both soft AND extra tough. VibraZilla is an amazing sensory tool for self-regulating oral input, oral desensitization, and for addressing other oral motor facial challenges for oral sensory seekers or those who have oral defensiveness (hypersensitivity to food textures, have difficult tolerating tooth brushing, or other oral input challenges). Comes with an “AA” battery and 3 silicone ID tags.
