A cartridge is small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write!

It's pretty easy, but it may be best to explain in video format. You can learn more about how to actually install an ink cartridge on our blog, or in this video tutorial:

There are two main groups of ink cartridges: standard international (available in short and long sizes), and proprietary (which only fit that particular brand).

You can read which cartridges fit a given fountain pen in that pen's product description or Tech Specs. You can also check out our Cartridge/Converter guide for general brand guidance if you’re unsure.

To locate pens that fit each size of ink cartridges, click on one of these links:

• Standard International Short
• Standard International Long
• Proprietary

Yes! You'll need an ink syringe, but in general it's pretty easy to do.
