50 Caliber Desert Camo Pen
No, not a missile, but a pen for the veteran or military enthusiast. First developed for the Browning, a .50 caliber machine gun in the late 1910's, the cartridge used in this pen is commonly used in the military. This pen uses an authentic .50 caliber once-fired brass cartridge with its natural patina with desert camo projectile and takes a Cross style refill. This is a large heavy pen, and has no clip for a pocket.
