The Meisterstuck Solitaire Doue Blue Hour Classique ballpoint pen from Montblanc introduces itself as a precious, blue lacquered Solitaire product with platinum-coated fittings. The magical hour between daylight and night - the Blue Hour - creates a smooth contrast and breathtaking mood, which served as design inspiration. The hexagon pattern on the barrel reflects the refraction of lights and night traffic in urban cities.
