AGE: 5 YEARS TO ADULT
Squeeze this quality silicone gel filled ball covered with a durable Lycra fabric to relieve stress, fidget, or to strengthen your grip. Its semi-firm consistency can provide variable resistance training for the fingers, hands, wrists and forearms. It is about 57 mm (or a 2-1/4 inches) in diameter. It feels quite ‘squishy’ and is easy to depress initially, but can take much more strength if you try to flatten it out all the way, which enables you to build strength in the fingers and forearm. Non-toxic.
