Ink Cartridges

Unraveling the Mystery!

This section of our Ink Facts page is designed to help you figure out which cartridge will fit your pen. Remember that not all fountain pens take cartridges, some pens will fill from only from an ink bottle.

This list is by no means complete! If you have a pen not listed here that uses cartridges, drop us an email and let us know about it. pendemonium@gmail.com

Standard International Cartridges

Standard International Cartridges fit many, many fountain pens! Below is a list, but it is by no means conclusive and there are certain exceptions as noted below. Most, but not all European pens will use standard international cartridges.

Standard short international cartridges measure 1.5inches (39mm) in length. Outer dimension of nipple width is 4mm, the inner width is 3mm. The diameter of the closed end of cartridge is 7mm. You may find slightly different tolerances among the different brands, but all are VERY close to these dimensions.

Many fountain pens that use standard short international cartridges will allow you to "piggyback" two cartridges in the barrel. This means you insert one cartridge into the nib/feed unit to use. The second cartridge is inserted nipple end down into the barrel so that the two flat closed ends of the cartridges flush up next to each other. Now you have a spare cartridge!

Proprietary Cartridges

These companies make pens that will ONLY take their cartridges, no others will fit, they are proprietary cartridges. Once in awhile, people get in a pinch and try to SHOVE a different cartridge into one of these pens. It might work, but be forewarned, you're just asking for a leaky cartridge, or even possible damage to your pen.
