Montblanc Ballpoint StarWalker SpaceBlue Metal. Starwalker Space Blue looks beyond planet earth and turns towards the stars and the galaxy. Utterly masculine and futuristic, this new Starwalker collection brings a new look for the metal barrel, with a design that recalls the intricate structures of the Widmanstätten Pattern, one of nature's most hypnotic creations. All metal parts are coated in dark ruthenium, accompanied by a deep space blue subdome on the cap top, recalling the hues of a starry sky, over which the Montblanc emblem floats.
