The Cap for this exciting new Space Pen model is an actual .375 H & H Mag Shell.
Fisher's other Cartridge Bullet Pens have actual bullet casings that are raw brass. This is their first release where the bullet cartridge has been plated with Nickel Silver. What a great look in the hand! The portion of the pen that contains their PR (pressurized refill) cartridge is plated with Copper Zirconium Nitride.
