Staedtler Blending Stumps are an indispensable drawing tool for all type of drawing. Use to smudge or blend marks made with charcoal, chalk, pencil or pastel crayons.When blending, a stump can be held at different angles to increase the surface area that contacts the paper. Keep the tip of the stump clean using sandpaper. Sandpaper can also be used to re-sharpen.
