The Souverän M100
is the flagship Pelikan pen.
Not only is it large, it's heavy. What sets this pen apart is the massive 18ct gold nib. It's not a flex nib, instead it is an inordinately flexible stiff nib. People bitch about the quality control of Pelikan nibs. I've never had a problem and this pen is one of the smoothest writers I own. In broad (B), it lays down the perfect amount of ink.
