Oh, I loved these things. In junior high, I drew everything with them. When they started making them with refills, I figured out that I could refill the refills and use them until the point was more of a region.
They’re especially great if you’re going to reproduce your artwork right away and throw out the original, which will fade and discolor over time and (as noted above) totally disfigure itself for a drop of water. I went through a bunch of different pens trying to find one that was unfading and colorfast, and ended up with my high school sweetheart, the technical fountain pen.
I just wish I could still get a couple of Rapidographs that look like lovely, fat fountain pens you’d see in the pocket of some banker. Those were the best.
