Souverän is the classic from Pelikan. The production of the tortoiseshell coat is subject to an elaborate process, as a striped piece of material is made from cotton material in many steps according to a recipe specially developed for Pelikan, which is bent and then cut to contour with a diamond. The special feature of the tortoiseshell material is the slight transparency of the material and the different colour nuances that give the material its shimmering effect. The gold-plated rings on the filling grip and cap are fitted with the utmost precision before the writing instrument is polished to a high lustre. The slightly springy, typical Pelikan beak clip gives this high-quality writing instrument its unmistakable design. The Souverän M400 piston fountain pen has a 14-carat bicolour gold nib and is available in EF, F, M and B nib widths. The F nib ensures fine writing and is particularly suitable for handwriting with smaller strokes.
