A number of the different fountain pens we carry will accept any international short ink cartridge.

This is a general term used to describe ink cartridges in this same size and dimensions. We have compiled a list of all the different brands we carry, for convenience.

1. Pelikan Fountain Pen Refill Cartridges 2. Kaweco Fountain Pen Ink Cartridges 3. Waterman Mini Cartridges 4. Ohto Fountain Pen Refill Cartridges 5. Rotring Brillant Fountain Pen Ink Cartridges

It is always best to ensure compatibility by sticking to the same brand of cartridges as the fountain pen you are trying to fill. Sometimes, even though these cartridges are all relatively the same size, other brands do not work as well with other fountain pens.

(Cartridges in above photo listed in order from top to bottom: Rotring, Ohto, Waterman, Kaweco, Pelikan) For example, the Pelikan cartridges have a slightly wider opening than the Kaweco ones, making them prone to leaking inside a Kaweco Sport fountain pen.
