ARK's Grabber XT is an innovative oral motor chew tool. It's "Xtra Tough" - recommended for mild to moderate chewing / for those who exert more jaw pressure. Use it to exercise the lips, tongue, cheeks, and especially the jaw, allowing the mouth to learn and grow strong through oral exploration. It also provides a safe alternative to chewing on fingers, nails, pencils, etc. It features bumps and nubs along its surface that provide additional tactile input and sensory stimulation. Highly recommended for individuals with oral defensiveness and/or food aversions to encourage texture acceptance and normalize sensitivities. Made in the USA out of medical grade, FDA compliant materials that contain NO lead, phthalates, PVC, BPA, or latex. Please note: This product is not a toy. Although these chew tools are made out of sturdy, medical grade materials, no chew tool is indestructible. Some individuals (particularly those with heavy oral needs and aggressive biting/chewing) may be able to damage the tools - how long they last depends on the sensory needs of the individual as well as other variables (stress/anxiety levels in their life, their jaw strength, if a sensory diet / other calming strategies are in place, etc). Please supervise at all times and replace if necessary when the item shows signs of wear and tear. For the toughest chew tool that lasts the longest for avid chewers, search for ARK's Y-Chew XXT.
