My brother uses those, I think - he does graphic design work, among other art.
I want a new dip pen and a decent selection of nibs. A lot of mine ended up rusty and ruined. :-\ It’d be nice if we had a good art store nearby, like the one we had in Fort Collins. That was a really nifty place...all sorts of sketch pads and books, different kinds of ink and paint and pencils and pens...
Nice.
