Thing is, I can't argue too much. I'm not here to tell people what not to use, just what I prefer going forward.
All of my early work (High School to probably College) was with various forms of ballpoint pens so I know they work well for that.
I've just discovered that I far prefer the writing experience of fountain pens. I have not explored them for drawing specifically yet. I have sketched out a few little pictures with some of mine, but nothing serious yet.
I guess my only gripe is that they're cheap and made to be thrown out one they're used up which I don't like from a "let's not make unecessary amounts of garbage" perspective.
nostr:npub16jad3sjdf0hynxhmpzpsuuwazqlxrcq824kjpw3w7wr8ldt3xm0q0zq4nn pointed me towards these pen bodies that accept any ink refill. I would likely lean towards that if I were to want a pen body that accepted rollerball refills.
Then it's "my pen" and reduces the garbage I mentioned before.
