The Schon DSGN Pocket Six Faceted Brass is made from brass and then faceted, to give it it's unique look and structure. The brass will develop a patina over time.
The Pocket Six is a very small pocket pen, which needs to be posted to use. Because of the good treading, it posts very quick and then makes it a full size pen, with a number six size nib.
It uses standard international cartridges.
