• ABOVE AND BEYOND RECOVERY - The Finger Master is not just for athletes and musicians (e.g. guitar finger exerciser). After any sort of hand or wrist surgery, or if you suffer from debilitating arthritis or carpel tunnel, pain medication and joint supplementation can only go so far. Exercising your fingers and hand help to maintain flexibility, strength and mobility in manual dexterity. This will also relieve pain by strengthening supporting muscles that take pressure off of joints.
• The Finger Master is the only hand strengthener that uses soft, malleable rubber for supreme comfort and a quality copper core, avoiding the stiffer, cheaper steel, for maximum comfort and superior durability.
• Highly versatile and fully adjustable hand exerciser and finger strengthener - select different tensions for each finger and thumb ranging from extra-light (3lb) through to heavy (8.5lb).
