This is a pen made from a .50 Caliber casing. The end of this pen is made with a piece of dark burl wood with a blemish that looks like a heart. This comes with a pen case that looks like a tactical gun case where one stores a rifle or bow. The ink is a cross refill that can be bought at any office supply chain. The pen unscrews in the middle to change the ink, making it a gift to last many years.
