Overview

The Montblanc StarWalker BlackCosmos Doué fountain pen explores the depth of space through glossy black resin, a carved metal cap, and dark PVD details.

BlackCosmos looks to the depth of space through a contrast of surfaces. Glossy black precious resin forms the barrel, while the metal cap has a carved finish and the details are coated with black PVD.

The ruthenium-plated 14k gold nib keeps the same dark tone. Above the cap, the Montblanc emblem appears to float inside a translucent dome through the patented StarWalker construction.

The fountain pen is made in Germany and has a screw-on cap. Capped, it is 135.7 mm long and weighs 34.85 g, with a 14.9 mm barrel width.
