Fountain pen ink cartridges in different colours

Ink cartridges make it easy to fill a fountain pen without using bottled ink. Insert a compatible cartridge into the pen, allow the ink to flow to the nib and you are ready to write again. Replacing a cartridge also makes it easy to switch to a different ink colour.

When choosing ink cartridges, the size and compatibility with your fountain pen are especially important. Many fountain pens use standard short international cartridges, but not every brand or model uses the same format. Platinum, for example, uses its own ink cartridges. An adapter is available for Platinum fountain pens that allows standard short international cartridges to be used.

What should you consider when choosing?

• Compatibility — check which type of ink cartridge is suitable for your fountain pen
• Size — standard short international cartridges are widely used, but brand-specific formats also exist
• Colour — choose from familiar writing colours to more distinctive shades, depending on the available range
• Use — cartridges are practical to carry and easy to replace when the ink runs out

With the right ink cartridge, you can easily keep your fountain pen filled and vary your ink colour whenever you feel like it.

Frequently asked questions about ink cartridges

Does every ink cartridge fit every fountain pen?
No. Always check which cartridge format your fountain pen uses. Many models accept standard short international cartridges, but some brands use their own fitting or format.

Can I change ink colours?
Yes. Let the old cartridge run empty or remove it and clean the pen if necessary before using a different colour. This helps prevent unwanted mixing of ink colours.

Can I use standard short ink cartridges in a Platinum fountain pen?
Yes, with the appropriate Platinum adapter. It allows standard short international ink cartridges to be used in a compatible Platinum fountain pen.
