Blue IronMind EGG (firm): Put This Potent Hand Strengthening, Stress Reduction and Active Rest Tool in the Palm of Your Hand

Use for strength, conditioning, active rest, rehabilitation or relieving tension. Can help eliminate bad habits and lower blood pressure. Egg-shaped for a natural fit in your hand—approximately the size of an avocado, not a walnut. Measures 3"" long and 7-1/4"" around the widest part. Soft enough give to be comfortable and yet perfectly at home in the world’s strongest hands—crush it as hard as you would like, as often as you would like. Has a little less give than the IronMind Green EGG.. Add a new dimension to your grip training. Made of a 21st-century polymer that is easy on the soft tissue of your hand and retains its shape. Made in the USA by IronMind, grip central since 1988
