 Montblanc is a German luxury goods company, founded in 1908 by Claus-Johannes Voss, Alfred Nehemias and August Eberstein. The company began as a manufacturer of pens and continued so until 1977, when it was bought by Dunhill. Montblanc then began to specialize in luxury goods – fountain and other pens, watches, leather goods, fragrances and eyewear - which it sells around the world.

The logo is a six-pointed white star, which resembles the snowy peak of Mont Blanc as viewed from above.
