This robust Ark Therapeutic Grabber is perfect for zeallous chewers. The XXT stands for Xtra Xtra Tough! The material used in this variant is even more durable than the trendy Ark Grabber XT, but still buoyant with enough bounce for safety. The Ark Grabber XXT is a superb workout for the mouth. It can tame oral fidgeting, tooth grinding, thumb sucking or food repulsion. It provides a safe diversion from chewing on hands, pencils, rubbers etc. It is helpful for those fed through a g-tube as they are prone to having chewing urges.
