These bold cufflinks will give you a reason to dress up. Made from recycled bullet casings soldered onto brass or pewter bases and given an antique finish. Choose from Antique Brass or Antique Silver color. Calibers used are 9mm, 357, or 40 cal. All of our bullet casings are gathered from shooting ranges. None of them were used to hunt animals, commit crimes, settle scores, etc. We aim to glamorize recycling, not violence.
