These are pretty decent quality. Compared to the rotring, the levenger are a bit shorter, thicker, heavier. The name levenger in no where as cool as rotring (!!!, I know very shallow, but..). Also the knurled cap/bottom is very cool on the rotring. On the down side, the rotring is very hard to find, especially the better early editions, and are ridiculously overpriced if you do find one. side by side pic.
