Yeah, it's dead simple, google "space pen cartridge" and you'll see. Also, I've not had the pen leave stains when using it.

omegant seems to think you're refilling the cartridge, rather than replacing it.

Yep that was my initial impression, I checked the site and the cartridges are quite inexpensive. I'll buy one to try.
