This metal cuff is heavy duty, but still comfortable to wear. We can put any combination of bullets/calibers in a cuff, but the most popular is a shotgun shell in the middle with smaller calibers on each side. The entire cuff is hand polished stainless steel and the bullets are first precision fit into medical grade stainless steel casings, before being expertly attached for maximum sturdiness. The underside of the cuff is smooth for a comfortable fit on the wrist and slightly adjustable. We have a myriad of Swarovski stone colors to choose from to give the steel cuff more sparkle for yourself or that special someone.
