Cartridges are the most straightforward way to refill fountain pens. They are easy to carry, simple to install, and don’t spill. Refillable brush pens and markers also often use cartridges, which work the exact same way as fountain pen cartridges. This article will show you how to install ink cartridges in any pen that uses them. If you want to learn about other ways to put ink in a fountain pen, read our Guide to Fountain Pen Filling Systems. It explains how to use the most common fountain pen filling methods and the pros and cons of each.
The first step to using a cartridge is to find the opening. You can usually identify the correct end of a cartridge by its cup-like rim. Sometimes you may even see a metal or plastic ball inside the rim to act as a seal for the ink. If there is a ball, it will be pushed in when the cartridge is punctured. It then functions as an agitator bead to improve ink flow by breaking the surface tension that causes ink to cling to the sides of the cartridge. The pictures above show some of our most popular refills.
