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.

In 1950, the model 400 was launched. With its green-striped sleeve, it has become a world-wide symbol for the brand of Pelikan. In the eighties, the series was baptized Souverän, though popular lore has taken to calling it by its nickname Stresemann, because the state secretary of the “Weimarer Republik” was famous for his striped suits... . After the black and blue model of 1995, since 2003, a black-blue-silver model established itself as another classic pen. It also has the typical sleeve.

If you love classics, you own a Souverän writing instrument.
