An awesome looking Concava pen that I call the "In and Out" pen as the upper barrel shape goes in and the lower shape goes out making one fluid line in the shape. It has a twist mechanism to advance the point. This pen takes a Cross type refill and comes with a black one. After hand turning this pen it was finished to a high gloss durable finish. The wood is Exotic Zebrawood. All the metal parts are all plated with 24K Titanium Nitrade which is very durable and has a lifetime warranty.
