Souverän – A world-famous classic. The transparent casing is subject to an elaborate process. The material of the casing consists of high-grade resin and it takes month until it is finished, whereupon the tailor-made plating is curved and cut into a contour using a natural diamond. The one-piece cap and filling knob rings, each with a glossy and satin finish, give this fountain pen an extraordinary look. The green-transparent components allow a view of the piston mechanism and also the ink level.
The fountain pen with M800 piston filling mechanism consists of a 18-carat bi-color gold nib with rhodium trim
