The Conte' Pierre Noire pencil has a soft, smooth lead with a black that is dense, rich, deep and indellible. The matt lead has an easily softened look. This pencil is particularly well suited for nudes, landscapes, laying rapid sketches, drawing and outlining and can be used on media such as sketch paper, linen, canvas and kraft paper. Use either with a sharpened lead for lively and accurate drawing or with a half-worn lead for more spontaneous and free work. Pierre Noire pencils can be sharpened with a rasor blade or knife to form a chisel point.
