In the year 1929 Pelikan was the first company in the world to introduce the differentiated piston mechanism. This technique causes the spindle inside the fountain pen to turn quicker than the end piece of the barrel, with the help of two different threads. To this date, this fountain pen exists in many different variations, and though it has been developed in design and technical details over time, the basic mechanism remains the same.
Only few years after the first Souverän model was launched on the market, the Souverän in black was presented in 1985. The main difference between this pen and its predecessors is that the sleeve is not striped. The barrel is made of entirely black high-grade resin. The view window of the ink container that is set off in a shade of transparent green as well as its gold plating give this fountain pen an individual character and the nostalgic aura of an original classic pen.
If you love classics, you own a Souverän writing instrument.
