All of our Ammo Bling Jewelry is made from recycled bullet shell caps. Please see the accompanying photo gallery for size comparison. This is a three in one bracelet. You can wear them one at a time or all three together. One ring holds a 45 caliber silver shell cap. The second ring holds a 12 gauge gold shell cap and a third ring holds a 20 gauge silver shell cap. Holy guacamole it’s a triple play.
