A trademark identified with Montblanc is the white stylised six-pointed star with rounded edges, representative of the Mont Blanc snowcap from above, the symbol being adopted in 1913. The number "4810," the mountain's height in metres, is also a commonly recurring theme.
Recently, it has been deliberated that the logo was updated by removing the name and using the star only. This was to avoid any mix-ups from happening as the brand's name was adjusted from two words to one.
The star is also referred to as an edelweiss, an indigenous perennial that grows in the alpine forests and mountains of Europe. Less romantically, the star is also referred to as "the bird splat" by some fountain pen collectors.
Special and limited editions
Next to various Limited Editions like the Patron of the Art Series (e.g. Francois 1er  with only a few hundred of them being produced around the world, there are some Limited Editions produced from editions of 4810 (the height of Mont Blanc) to those in tens of thousands.
The Patron of the Art (POA) Series are found in editions of 888, increasing their appeal in Asian markets. These models are intricately adorned in diamonds, rubies, and other precious stones into precious metals typically in 18K gold. A signature mark on these include a Mother of Pearl Montblanc Star adorning the cap.
Although cheaper, the Montblanc Writers Edition has been profitable. These pens are launched each year, commemorating the life and work of a particular writer, with their signature engraved into the cap of the edition. Usually, a symbol of their most distinguished work is engraved onto the nibs, of the fountain pen versions. Montblanc use "aged resin" in the caps of the pens in this series, to give the Montblanc star an 'off-white' or 'cream coloured' appearance, thereby ensuring a contrast in colour when next to models from their regular production line-up.
Apart from a serial number the Limited Edition pieces carry a distinct number placing it within the release of the edition, i.e. 1/888 would be the first pen produced of an edition of 888 pens. Editions include Patron of Art, Writers Edition, Special Theme Edition, Annual Edition, Donation series and America's Signatures for Freedom. The Donation series includes some limited Editions like the 2009 released Signature for Good limited edition. Montblanc donates parts of its proceeds to UNICEF. They claim to guarantee a minimum of US $1.5 million worldwide within one year.
