50 Cal Machine Gun Cartridge FLIP Rollerball Pen Kit
50 Cal Machine Gun Cartridge FLIP Rollerball Pen Kit
Turn a pen that stops conversations with the 50 Cal Machine Gun Cartridge FLIP Rollerball Pen Kit. An authentic, once-fired 50 caliber brass shell serves as the holder, sleeve, and desktop stand — flip it open to reveal a precision rollerball pen inside. O-rings seal the refill chamber for maximum refill life, and a solid copper bullet tip completes the authentic military aesthetic. Large, impressive, and unlike anything else on the market.
What truly sets the 50 Cal FLIP apart is the pen itself — the real shell casing IS the product. You're not making a pen themed after ammunition; you're incorporating an actual once-fired 50 caliber cartridge into a functional, desk-ready writing instrument. Easy single-tube construction makes it approachable for turners of any skill level.
