I’ve used an ECO and while it’s not my favorite pen, I have nothing bad to say about the nib (I believe mine was a fine as well). The way FP’s write can vary dramatically between different inks though. I’d recommend first trying out the ink you have and seeing what about it you don’t like before researching other inks.

Just asking out of precaution, but are you sure this bottled ink of yours can be used with fountain pens? Even if it is, it’s best to be careful with a fine nib (I’ve learned the hard way).

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.

That's lovely! I do the same now with a few friends. Postcards, letters, etc.. It's a blast. Just got some Strathmore letter paper too. So much nicer than what I was using.

I’ve got a whole box of inks, many colors I adore using, but for any functional usage I find I’m always reverting back to Platinum Carbon Black.
