Cartridges isn’t something.I have used a lot with my fountain pens. I used to use them back in the very early days. But I soon moved over to bottled ink and piston fillers and converters.

But I have since the summer gotten a few of pens where I do use them: Kaweco Sport. I have converters for them, that I haven’t tested out yet. I have just continued using cartridges with them.

The original plan was to use cartridges, but I should probably test out the converter. Where it leads all depends on how much (or little) ink I can get in them. If it is too little I’ll probably just stick with the cartridges for the convenience.
