Designed by a brush-using calligrapher, the Yoropen has a gooseneck kink that places the pen tip perpendicular to the paper, rather like a plotter. This arrangement apparently makes it easier to modulate the pressure and ink flow.
Another neat design twist, is, literally, a twist: the soft rubber grip is pliable enough to be twisted into a whirl for the sake of comfort, and lefties can of course twist it in the other direction.
You can also rotate the Yoropen so that the pen tip is out of the way and you can actually see what you're writing. This might not be a big deal when writing English, but comes in handy when scribing the more complicated kanji or Chinese characters.
