Review on Isoflex 32060 IsoFlex Attitude Stress by Ryan Hawkins

Bought this for my 10 year old son to use at school to stop biting his nails. He pretends a little and sometimes gets a little restless. He loves to. That's what he wanted, not just a soft ball to relieve stress. I myself liked this feeling very much. Inside was a sand-like substance that felt like rubber on the outside. The little picture outside is cute too. It looks like I could benefit from strengthening my injury-prone wrist. I will buy him (and probably myself) another one.
