Same size and style as the Bullet Keychains but these are inlaid with neodymium type magnets which are known to be a lot stronger than your typical magnets you find at your local craft stores. For a more cleaner and sleeker look and finish. Anyone can glue a magnet behind a bullet but these are still works of art all fused into one. Please contact me for multiple piece discounts. Many more different calibers to come!
