I have to disagree with some of the reviews written here. This mechanical
pencil, in my limited opinion, is WAY superior than the Rotring 600. I had the
two of them, and I fell this one superior in almost every aspect. At least for
my tastes this is a better pencil. Is longer, wider, and lighter than the
rotting 600, AND it's pocket safe. I written a full head to head comparison in
my site, feel free to check at nnil.es
The only negative point is the price, other than that, I can't recommend enough
this puppy. But black of course!.
