This starts with a real nickel .338 Winchester Magnum casing, with the primer removed. It's then drilled right through the real bullet so the pen tip can extend. Then mule deer antler is turned down for the top and the new finish I've finally perfected is put on (5 coats), then it's sanded down to 12,000 grit for a glass-like finish. The casing is powder-coated so it will not corrode, but will remain shiny. This is a gorgeous pen for anyone, but hunters obviously will flip for this pen. It's a medium-sized pen. This pen is absolutely perfect for engraving with someone's name, or a company logo, or both.
