When Pelikan registered the patent for the differential piston mechanism in 1929, nobody knew that the same technique would survive for decades . . .
But to this day, only a few small changes have perfected the piston mechanism, and the Demonstrator model, which was first introduced in a smaller 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 has decided to launch this Special Edition, the Demonstrator in the size 1005, which is the biggest available Pelikan fountain pen size.

The nib is made of 18 carat gold, entirely covered by rhodium, to give a silver impression. The clip and the rings are palladium plated. To obtain the completely transluscent barrel, every part of the production machine has to be thoroughly cleaned in a time consuming process, so that not a single color particle remains. Each fountain pen is packed inside an attractive gift box.
