Welcome to The Pleasure of Writing!
The Cap of this exciting Space Pen model is an actual .375 H & H Mag Shell. Inside is a Raw Brass Cartridge Space Pen. It makes for a special gift for the hunter or outdoors enthusiast.
Please note! This pen is RAW Brass—just as bullets are—meaning there is no finish on the brass. Over time a nice patina will develop, giving each one its own unique look.
Fisher Space Pens recommends you never fly with your .375 Cartridge Space Pen, as TSA sometimes won't believe it's a writing instrument!
