The 400 and 405 designs are a diminutive 12.7cm in length, making them the second smallest in the Souver n range, perfect for writers who prefer the feel of a smaller pen. The 400 features the classic 24-carat gold accents. - Pelikan's distinctive striped barrels are available in red, black, green and tortoiseshell-white, with the 400 range also offering a solid black finish of high grade resin. - The striped material that makes up the distinctive barrels of the Souveran range is composed from a celluloid cotton base using a formula developed specially for Pelikan. The layers are slowly built up over months before being sliced and shaped using a natural diamond. - The resin cap features characteristic double rings precisely integrated to present a seamless transition between materials. The glossy barrels are complemented to great effect with 24-carat gold. The clip of the Pelikan represents a beak, another characteristic unique to this historic manufacturer; one of the oldest trademarks in Germany. - Pelikan especially pride themselves on their expertise in creating nibs, inks and feeds; their mastery over these essential components enables them to create fine-writing instruments of the highest quality..

The pen features an ink view window and uses a differential piston fill mechanism constructed from brass. Available in four nib widths EF, F, M, B. Also accepts standard ink cartridges.
