This necklace is made using a real, previous fired brass 9mm bullet casing. The casing has been drilled, primer removed, and the bullet tip reinserted and hung from a nickel free chain. The entire bullet piece measures about 1 inch long. Since real bullets are used manufacturers may vary and bullets may have unique markings on the casing from being fired. Dimensions listed are approximate. Sizes, colors, and other characteristics may slightly differ due to the handmade nature of our products..
