This is (one) thin blue line twist bullet pen. It's made from two real once fired .308 bullets. Great for any law enforcement officer. They have been powder coated with a flat black finish and has a police blue divider ring. This has a cross pen inside with a replaceable ink cartridge available from amazon and any office supply store, so this pen can last a lifetime. You get FREE SHIPPING and FREE ENGRAVING with this item. Engraving is up to 12 characters on the top bullet all CAPS look the best. 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.
