50 caliber bullet cartridge pen kit. Includes an authentic .50 caliber once-fired brass cartridge.

This is a real, once-fired shell and will contain some tarnish, marks and small dings – this is normal. Will make a great gift for any outdoorsman or military enthusiast. First developed for the Browning, a .50 caliber machine gun in the late 1910’s, the cartridge used in this kit is commonly used in the military.
