50 Cal Machine Gun Cartridge FLIP Pen Kit
Build a pen that doubles as a conversation-stopping desktop display with the 50 Cal Machine Gun Cartridge FLIP Pen Kit. An authentic once-fired 50 caliber shell acts as the sleeve and stand — flip the handcrafted wooden pen out for a fully functional writing instrument with a solid copper bullet tip. It's bold, it's unique, and there's nothing else like it on a desk.
What makes the FLIP Kit truly special is the engineering: O-rings seal the Parker-style refill inside the cartridge for an impressive long refill life, while the pen itself slides in and out with a satisfying, purposeful action. The included 50 cal shell is the real thing — once-fired brass, heavy in the hand, and unmistakable in presence. This is a project that non-turners will pick up and examine every time they visit your booth.
