Fountain Pens

In part just to be able to write with my fountain pen, I used to write long letters to friends in different parts of the country. Then email came along, and I mostly used my fountain pen to take lab notes in grad school and to do derivations of formulae. Now I use it to write in my daily planner or to make margin notes on post-its in the books I read. I love how the slipping friction of the nib feels on paper, but I don't have much use for pens at all anymore. I don't have lab notes or need to derive formulae, and I don't have that much to write to anyone anymore.
