Pelikan Mechanical Pencil D400 Sovereign 1980s Black & Green - W.Germany Souverän - A world-famous classic. Even today, this classic with a black-and-green pinstripe sleeve is still considered a symbol of the Pelikan brand worldwide. The production of the Souverän sleeve is subject to an elaborate process. The typical, striped material is made out of cotton based on a formula developed specially for Pelikan. It takes month until the block providing the stripes is finished, whereupon the tailor-made plating is curved and cut into a contour using a natural diamond. The rings are then integrated into the cap and barrel with the utmost precision. The writing instrument is then polished until it reaches a brilliant luster. Shipping comes with tracking and trace.
