18-20" adjustable length gray imitation leather cord necklace. Pendant is a 9MM Luger bullet shell with a gray quartz stone. This product is made with recycled bullet casings, new beads, wire and findings. Bullet casings are cleaned and polished to a high shine. As with any brass product it will tarnish over time and handling, you can bring the shine back by gently shining the brass with 000 steel wool.
