The Pelikan Souverän M600 is a great middle series model to try out. It's not too big (like the M1000) and it's not too small (like the M200 series). It's a decent size, it's very comfortable and not heavy, it's very pretty, and the nib is a pleasure to use. The M600 has a differential piston-filled ink system and hand-crafted finely engraved 14K Gold nib. The Pelikan M600 Black Green features Pelikan's classic green striped barrel and gold-plated trim. The Pelikan M600 Black green fountain pen comes with the hallmark striped celluloid overlay that has been associated with Pelikan fountain pens for half a century. The cap band is engraved with "Souveran," and the material has a sparkling quality to it.
