A cartridge-shaped reservoir that allows you to use bottled fountain pen ink, when a cartridge would otherwise be your only option. Fountain pens that have this option are usually referred to as a cartridge/converter pen, or C/C for short.

These fountain pens all take a converter. Please check the individual product descriptions for if the pen needs a proprietary or standard converter.

You can also check out our Cartridge/Converter Compatibility Guide for general brand guidance.
