Cartridge Pen Kits

$ 14.95

Real brass 30 caliber casings and copper billets machined into nibs for the complete pen kits.

Complete Cartridge Pen Kit includes everything but the upper pen blank. We sometimes have available custom made TBC bushings for our cartridge pen kits, but if not, or you want to use bushings you may already have, please use the following information.


The lower interface of the upper blank uses a 30 CAL Bolt Action Bushing.  The upper finial uses a Euro or Designer finial bushing. The blank is turned to size and polished like a normal resin blank. Sand through the 12,000 grit Micro Mesh pads.  You can use a plastic polish after if desired, but it is not required. 


For the brass cartridge itself, you may want to polish with Renaissance Wax to prevent tarnish, or expect to polish often as untreated brass.
