The Copper Knucklebone Dexterity Toy is manipulated with the fingers with one or both hands to train dexterity, perform tricks, or to simply pass the time. The solid copper is much denser than nearly any fidget toy out there (besides our own WCu), so it's for more advanced users or those that want to build up your hand muscles.
