The wood is spalted macadamia nut. #6 Bock. Its a large pen about 5 3/4 inch long. The cap at the largest OD is about 15.5mm and the barrel at largest point about 14.5mm. Thanks for looking.
James,
I read several forums and can't remember where I got the idea but the pen sitting on a mirror reflcting a printed piece of paper in the background.
