Diplomat Cobra Black Guilloche Fountain Pen

Bold, tactile and unmistakably modern, the Diplomat Cobra Black Guilloché Fountain Pen brings a striking new edge to the brand’s reptile-inspired collection. Building on the success of the Viper, the Cobra retains its satisfyingly smooth magnetic cap while introducing a deeper, more pronounced guilloché pattern inspired by the scales of its namesake.

Crafted from durable metal, the barrel and cap feature a sophisticated matte black lacquer finish, complemented by polished black PVD trims for a sleek, contemporary contrast. The engraved guilloché pattern is more than a visual statement; it creates a distinctive tactile feel and offers enhanced grip for a comfortable, controlled writing experience.

At its heart is Diplomat’s renowned Excellence stainless steel nib, engineered in Germany to deliver an exceptionally smooth, consistent and reliable flow of ink. Available in Extra Fine, Fine, Medium and Broad nib widths, the Cobra can be tailored to suit everything from precise everyday notes to expressive, characterful handwriting.

Complete with a cartridge and converter filling system, the Diplomat Cobra combines premium performance, precision engineering and head-turning design in one distinctive writing instrument.
