I already had a pencil like this for years, but I just wanted my writing set is matched in black. I highly recommend it to all who regularly use a mechanical pencil. His grip is extra: it is "equipped" with a rubber ergonomic grip, this is a format "jumbo" (= thicker than a disposable mechanical pencil) and has a gum (which is no black marks!) Extra long telescopic. I do not buy the other, as the title says: for me the best mechanical pencil that I could use.
