The edition was issued on the occasion of the Montblanc 100-year anniversary in a run of 3 x 100 examples, 100 LeGrand piston fountain pens each in yellow gold, rose gold and white gold; the threefold 100 limitation refers to the three founders Voß, Nehemias and Eberstein. Barrel and cap show a guilloche of running-out Montblanc stars with inlays of mammoth ivory from the Siberian permafrost soil; the cap carries a specially designed 43-faceted diamond in star form, cast in acrylic. The 18-carat gold nib is colour-matched to the body with partly platinum-plated year number. The retail price is €15,000 per piece; further writing instruments (ballpoints etc.) do not exist; in Germany about 5 examples each are available.
