CNC engravings featuring Border Patrol, using real brass 30 caliber casings and copper billets machined into nibs for the complete 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.
