This is a special pen we make and as always there is only one of a kind. We make these blanks at First Due Woodworks.  At the bottom which you see very faintly going the long axis of the pen is strips of alumminum can from Coke. Coke the only good soft drink!!! The top is made up of Walnut, Oak and Maple. This is based off of a slim line pen and has the awesome Gun Metal pen componets!
