Montblanc Meisterstück Doué Geometry Champagne-Gold Classique Fountain Pen (118095). The Meisterstück Solitaire Geometric Dimension was born of the desire to unite Montblanc’s classic design with unique materials. This writing instrument, engraved with its three-dimensional geometric pattern with optical effect in a sophisticated champagne tone, features an 18K champagne gold-coated nib with special design, a champagne gold-coated clip and three champagne gold-coated rings embossed with the Montblanc brand name. Finished with the Montblanc emblem, it appeals to one’s individuality. And has a piston converter inside its black resin barrel.
