The Woodless Black Colored Pencil for Sketching, Drawing, and Shading We designed our pre-sharpened pencils in a way that helps you create broad strokes and shade large areas. The EE pencils contain both charcoal and graphite (50/50) for a deeper, richer color that adds dimension to your sketch. These shading pencils can produce a lot of movement within a drawing, as it’s a medium that’s also simple to layer. What We Love About Our Arteza Woodless Graphite Pencils: Rich black pigment. Won’t break off easily into pieces like other brands. Make producing broad strokes and shading large areas effortless.
