The best pencil I have used hands down. Capable of consistently producing both the lightest and darkest of marks, building up shadows perfectly with excellent adhesion to the page. Can be manipulated with stumps or smoothed with ease and without lifting pigment or leaving patchy areas. Everything about this pencil is the result of thoughtful expertise used to create as good a drawing tool for artists as possible.
Every time you use a pencil it most likely makes one of our forests in northern California that much smaller. A pencil like this is just about the only thing that makes that justifiable.
