Cerakote is a ceramic based finish commonly applied in the firearm and automotive industries. It is a highly durable coating suitable for metals, plastics, polymers and wood. The unique formulation used for Cerakote enhances a number of physical performance properties including abrasion/wear resistance, corrosion resistance, chemical resistance, impact strength, and hardness.

At Custom Casings, we follow the Cerakote application process. Casings are first degreased in an Acetone tank for 30 minutes. From this point on the casings are only handled with gloves on to avoid any possible contamination from bare hands. Next, the casings are sandblasted with aluminum oxide and put through a gas out phase for 60 minutes in order to evaporate any remaining moisture and solvents, and to bring any remaining oils to the surface. Casings are then racked, spray-coated with the chosen Cerakote color(s), and oven cured at 250 degrees for two hours. Once the casings are cooled they are individually inspected and assembled into pens.

Yes they can! We are not currently equipped here at Custom Casings to do this. However, your local engraver should be able to engrave your pen to personalize it for you.

At Custom Casings our primary concern is your satisfaction. We take personal pride in all of our products and we want you to know that we've got your back, We stand behind our materials and craftsmanship. If you ever have an issue with one of our pens or pencils that is beyond your control, we will make it right.

  • .308 twist pens use cross style ballpoint refills. These can be found at your local office supply or here at Custom Casings. To change, simply grasp firmly on each side of the center band and pull the pen straight apart from the middle. Unscrew the plastic and remove spent refill, insert and screw in new refill, and press casings back together again.
  • .308 click pens use Parker style refills. Simply unscrew the tip of the pen, pull spent cartridge out, transfer the spring over to the new refill, insert new refill into pen, and screw the tip snugly back on.
  • .300 mini blackout pens use mini style refills. The replacement procedure is the same as the .308 twist pens with the exception of a small threaded metal cap on the end of the refill itself that must be transferred to the new refill.
  • .50 Caliber pens (unless stated otherwise) use Parker style ballpoint refills. These can be exchanged by unscrewing the copper tip of the pen. Remove spent cartridge, transfer the spring over to the new refill, insert refill, and screw tip back on. 

Brass and nickel tarnish naturally over time. If you would like to bring the shine back, any metal polish should work (we are partial to Flitz). Just take care to keep polish off of the trim parts, particularly if you are using an abrasive polish, as it could eventually rub the coating off of the trim.
