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. Designed and made in the USA by ARK Therapeutic. Medical grade. FDA compliant. NO lead, phthalates, PVC, BPA, or latex. CAUTION: This product is NOT a toy - use should be supervised at all times. Although these chew tools are sturdy, no chew tool is indestructible. Wear/tear may be expected given the nature of the intended use. How long they last is typically equal to the amount and intensity of the chewing, as well as other variables (such as jaw strength, stress/anxiety levels, if other sensory strategies are in place, etc.). While for some people a chew tool will last forever, for others with heavy/aggressive oral needs, they may go through it very quickly. Please supervise at all times and replace if necessary if the item shows signs of wear and tear. For the longest lasting chew tool for avid chewing, see ARKs Y-Chew XXT.
