Bullet necklaces using deactivated rounds of the caliber of your choice. Necklaces come with a 24" dog tag style chain that can be shorted to the desired length just by snipping the chain on the non-connector side. Many caliber options - if I don't have the one your looking for, contact me as it is possible I can set you up with it. You will receive 1 necklace per purchase unless otherwise ordered.*Note: Bullet may contain lead, though it is covered with a copper jacket so is it kept away from user. WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer, birth defects, or other reproductive harm.
