NEW! Our "toughest" hand and finger strengthening tool yet! XXT Hand Squeezers are a superb therapy tool for teens-adults. They feature a 33 lb. tension rating and soft foam handles that make for comfortable gripping. These portable exercisers make an effective stress reliever tool for home, school, the office, sensory study breaks, and while watching tv. A great hand workout (that's too high level / difficult for most children and/or those whose hand strength is significantly lower than average). A quality squeeze tool at a great price!
