I own several Sailor fountain pens, but I’ve always been interested in their Realo model. I never bought one because I don’t like the colors offered by American companies (black, maroon, and nibs.com has a special edition in yellow). Luckily, I stumbled upon a Japanese-only edition Realo in the Sale forum on Fountain Pen Geeks. This special Realo is called “Tenku Gensou” which I believe means something like “sky illusions” (someone who speaks Japanese please correct me if I’m wrong).
