Good to know. TBH I haven't checked. I have some cartridges too (for a different, cheaper fountain pen) but if none of those work, I'll scout for options.

What got you into writing letters?

I’m in a long distance relationship at the moment, so one of the things I try to bridge the distance is sending letters! That’s how I got started, but now I’ll send letters to any of my friends (or anyone really) that sends me a mailing address.

One thing I strongly advise when it comes to writing letters with FP ink is to use waterproof/permanent inks. I had to learn that hard way that typical ink doesn’t handle rain well… Diamine just came out with a new lineup of permanent inks which I quite like, but the Platinum stuff (my favorite being Carbon Black) is quite good as well.
