The paper stump makes the difficult job of blending dusty media such as charcoal and pastel much easier and cleaner. Once the stumps get dirty and the points wear down they can be easily cleaned and re-pointed using a sandpaper block. Derwent paper stumps can be found individually or in a handy pack of 3 sizes ranging in diameter from 5.5mm to 10.5mm. The paper stumps are made from compressed rice paper and with a point at each end.
