Montblanc

Montblanc is a German maker of fine fountain, ballpoint, and rollerball pens. Their fountain pens take a standard international ink cartridge and proprietary piston converter. Almost all of their ballpoint and rollerball pens take proprietary refills. The only standard refill is their multifunction, which is a standard D, D1 refill. Jaymo and Monteverde both make refills that will fit their pens. Montblanc is also one of the most frequently counterfeited pen brands. If none of the refills below fit your pen properly, it’s most likely a fake.
