Which type of cartridge or converter does my fountain pen take?
Refilling your fountain pen is always a fun adventure, but it can be confusing at the start.
The majority of fountain pens will take a standard international cartridge or converter. Depending on the length of the pen (for example, Kaweco Sports are shorter pens) they may require a short standard international cartridge or converter, which has the same opening as a standard international cartridge but with an overall shorter length.
Other fountain pens require proprietary cartridges or converters, which are designed specifically to fit their brand’s pens.
Pen brands that require a proprietary cartridge are underlined below.

- Kaweco Sport and Kaweco Lilliput pens are too short to accept the long size Standard International cartridges or converters, but will accept the short size Standard International cartridges. The Kaweco-branded mini converters are slightly too long for the Sport models but are ideal for the Lilliputs. The Kaweco-branded squeeze converters will fit all but early Sport models. The early Sport models should accept a Monteverde-branded mini converter.
- Ohto Tasche pens will accept the short size Standard International only.
- Online branded cartridges have a special dual-ended function in which one end fits pens that take Standard International cartridges, and the other end is shaped to fit Lamy pens.
- Traveler’s Company pens will take the short size Standard International only.
Hero, Jinhao, Moonman and Regal pens can be inconsistent with which type of cartridge/converters they will take. Many models will accept a Standard International, however others seem to take unbranded, proprietary cartridges which differ from each other in small, undocumented ways.
CARTRIDGE/CONVERTER TYPE BY PEN BRAND
Aurora branded cartridge/converter
Aurora pens (sometimes Parker or Lamy)
Parker pens
Lamy branded cartridge/converter
Aurora pens (sometimes Parker or Lamy)
Monami pens
Lamy pens
- Lamy Z23 fits Persona model only
- Lamy Z24/Z28 fits Safari, Vista, Al-Star, LX, Joy, and ABC models
- Lamy Z25 is threaded and fits early Accent and Lady models
- Lamy Z26/Z27 fits all current production models (and, allegedly, some Parker pen models)
Pilot branded cartridge/converter
Namiki pens
Pilot pens
- Pilot Petit pens use Pilot Petit cartridges only
- Pilot Parallel pens can use standard Pilot cartridges and converters, but the ink in the Parallel branded cartridges is of a thicker formulation than the standard Pilot cartridges and is not recommended for use with non-Parallel pens.
- The Pilot CON-70 converter will only fit in Pilot Custom, Justus 95, and Kaküno models. It is too large for the Capless/Vanishing Point, Cavalier, Elabo, Elite, Falcon, Garance, Lady, Lucina, Metropolitan, Parallel, Penmanship, Plumix and Prera models.
Cross branded cartridge/converter
Cross pens
Monami branded cartridge/converter
Monami pens
Parker branded cartridge/converter

Parker pens
Platinum branded cartridge/converter
Nakaya pens
Platinum pens
Sailor branded cartridge/converter
Sailor pens
- Sailor Chalana pens require a Sailor Slim converter/cartridge rather than the standard Sailor converter
- Sailor Mini pens are too short to fit a standard Sailor converter, but will fit a (discontinued) Sailor Mini converter
This list is far from comprehensive, and many of the brands with proprietary cartridge/converter systems also have older or less-documented models with even more specific needs than the ones listed here. Hopefully, readers will weigh in with their expertise in the comment section below.
