Probably not, all your signatures will be with nice ink, sure, but they'll still look like ballpoint signatures rather than fountain pen signatures.

UniBall's vision elite pens shade like a fountain pen. I think it's mostly ink's behavior but it needs testing.

It depends if it’s the act of signing itself that is ceremonalized, or the quality of the ink on the paper.

What matters is that it appears to have been a fountain pen when the recipient receives it. That's probably a combination of ink viscosity, pressure on the paper, things like that.

Out of curiosity, what role/industry is that?

The Army - supposed to top and tail letters, especially social letters, with a fountain pen. Ballpoints are crass.

Social letters?

Invitations, letters of introduction, thank yous, things like that.

Thank you for that tiny glimpse into a different world.

FWIW, it’s going away with the newer generation, but anyone in France over the age of 40-50 from an upper middle/higher class education would likely follow similar etiquette. Not sure if it’s still the case, but French students were required to use fountain pens from 1st grade till at least high school when i was growing up (as a leftie, being schooled by old school teachers who made you redo any assignment that had smeared ink was painful).

Our son was still required to write with a fountain pen and was graded on penmanship. He was in the French education system to CM2 until we moved to the US 3 years ago.

Yes, been there done that, I was so relieved when I could stop using these f.. fountain pens. Really annoying to use as for lefties..
