This stunning bullet pen gives you the elegant rollerball feature of a high end pen, as well as the sportsman qualities of a classic bullet pen. The best known feature is undoubtedly the cap made to resemble a 12 gage shotgun shell. The cap is made of black onyx acrylic, this gives the look and feel of a solid color 12 gage shell. The multiple layers of epoxy we put over the wood is what creates the glossy finish you see. The body of the pen itself is turned on a lathe to be exactly the size of the pen hardware on either side Most prefer to write with the cap off altogether rather than posting on the back of the pen, this leaves the pen with perfect balance and comfort. The smooth writing rollerball delivers bold quality ink like you expect from a top tier pen.
