context_page_description: A fountain pen is a nib pen that, unlike its predecessor, the dip pen, contains an internal reservoir of liquid ink. The pen draws ink from the reservoir through a feed to the nib and deposits it on paper via a combination of gravity and capillary action. Filling the reservoir with ink may be achieved manually, via the use of an eyedropper or syringe, or via an internal filling mechanism which creates suction or a vacuum to transfer ink directly through the nib into the reservoir. Some pens employ removable reservoirs in the form of pre-filled ink cartridges.
context_section_description: Most European fountain pen brands (for example Caran d'Ache, Faber-Castell, Michel Perchin, DuPont, Montegrappa, Stipula, Pelikan, Montblanc, Europen, Monteverde, Sigma, Delta, Italix, and Rotring) and some pen brands of other continents (for example Acura, Bexley, Retro51, Tombow, and Platinum (with adaptor)) use so called "international cartridges" (AKA "European cartridges" or "standard cartridges" or "universal cartridges"), in short (38 mm in length, about 0.75 ml of capacity) or long (72 mm, 1.50 ml) sizes, or both. It is to some extent a standard, so the international cartridges of any manufacturer can be used in most fountain pens that accept international cartridges.
  Also, converters that are meant to replace international cartridges can be used in most fountain pens that accept international cartridges. Some very compact fountain pens (for example Waterman Ici et La and Monteverde Diva) accept only short international cartridges. Converters can not be used in them (except for so-called mini-converters by Monteverde). Some pens (such as the modern Waterman models) have intentional fittings which prevent the usage of short cartridges. Such pens can only take a proprietary cartridge from the same manufacturer, in this case the long Waterman cartridges.
