CNC Navy Dolphins Pen Kits

$ 24.95

CNC engravings featuring United States Navy Dolphins emblem, using real brass 30 caliber casings and copper billets machined into nibs for the complete pen kits. 

Complete Pen Kit with CNC Engraved Cartridge Casing includes

  • Complete lower half assembly engraved cartridge with copper billet nib
  • 7mm tube for the upper barrel pen blank (pen blank not included)
  • Gold titanium pen clip with finial top
  • Cross style pen ink refill

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. 

Cartridge engraved pen kits are made to order and may take 7-10 days to be ready for delivery.
