This stunning set of cufflinks is sure to make a powerful statement. Made from recycled bullet casings soldered onto brass or pewter bases and set with clear crystals. 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.
