NOW AVAILABLE! The birth of the .338 Lapua Magnum dates back to 1982, when an American company Research Armament Industries, RAI, in Rogers Arkansas, was asked by the United States Marine forces to develop a long-range rifle for sniper applications. RAI was a relatively small company, owned by the late Jerry Haskins, operating mainly in the field of defense technology projects. Officially the project was to develop a target rifle for 1000 yards, but in reality the purpose was more likely to develop a 1500m sniper rifle. The Cap for this exciting new Space Pen model is an actual .338 H Mag Shell. What a special gift for the hunter or outdoors enthusiast. Inside is a lacquered Brass Cartridge Space Pen. Please note! This pen cap is RAW Brass, just as bullets are. That means there is no finish on the brass. Each one will have it's own unique look. Over time a nice patina will develop. Also we recommend you never fly with your .338 Cartridge Space Pen. TSA sometimes won't believe it's a writing instrument! We want you to enjoy your Space Pen for a long long time.
