When Pelikan registered the patent for the differential piston mechanism in 1929, nobody knew that the same technique would survive for decades. To this day, only a few small changes have perfected the piston mechanism, and the Demonstrator model, which was first introduced in a different size just to show how it works, became a global success. Technically minded people are fascinated to see the mechanism „in action“ every time they refill their fountain pen . . . and so Pelikan decided to launch the 200-model as a Special Edition in 2012.
The production of the Demonstrator piston fountain pen provides many challenges for the production: Once the Demonstrator has been produced, every dust particle in the inside of the fountain pen is not only visible but can’t be removed anymore, therefore the production has to meet unusually high standards. The high-quality, transparent resin also has to be absolutely free of any color particles.
In order to make this fountain pen even more attractive, it was equipped with an additional ring at the top of the cap. This ring is plated with 24 carat gold, just like the clip, the rings, and the stainless steel nib. The nib is available in four sizes. Every fountain pen is offered in the attractive, blue gift box G5. This series is made in Germany with the Pelikan know-how of decades and is only available for a limited period of time.
