Drawing ink cartridges designed for the Staedtler Mars Matic range.
Most fountain pens nowadays are ink cartridge compatible, meaning that rather than having an internal reservoir, there is a removable cartridge that can be swapped out for a fresh one whenever needed. The benefits of ink cartridges are that they allow you to have minimal mess, and the ability to get writing again quickly and easily.
Ink cartridges come in all sorts of different sizes, and the one you need depends greatly on the pen, so we advise checking the product descriptions to find out which one you require. A lot of pens take what’s known as an international cartridge, which is a standard size.
They also come in many different colours, which means you can really express your creativity through your writing. If you really want to open up your world of ink, then why not look at converting your fountain pen so that it can be used with bottled ink.
