ARK's Grabber XXT is an "Xtra Xtra Tough" version of the standard purple Grabber. It's very firm, but still chewable - the best / longest lasting option for avid chewers, and/or for those who like to chew on firm/rigid items. 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.
