1950 was the year of birth of the model 400. Even today, this classic with a black-and-green pinstripe sleeve is still considered a symbol of the Pelikan brand worldwide. In the 1980s, the series was given the name "Souverän®".
This name continues to write history today, and will do so in the future too. Today, this fountain pen exists in many variations and, despite the continual refinements of the design and technology, its fundamental mechanics remain the same.
