This is a twist bullet pen. It’s made from two real once fired .308 bullets. They have been powder coated with a flat Army Green finish. The bullet is completely inert with the powder and primer removed and can never be reconstructed into a working bullet again. Its design and construction make it nearly indestructible. This is a fun and functional gift, great for groomsmen gifts or stocking stuffer. It can be engraved with one line of engraving up to 12 characters, all CAPS look the best.
