CNC engravings featuring United States Navy Master Chief emblem, using real brass 30 caliber casings to assemble into cartridge pen kits. Casings are not for beginners and requires previous experience or knowledge in building a custom cartridge pen. If this is your first time making a cartridge pen, we suggest you purchase the complete pen kit instead of individual casings.
