Perfect For Blending Charcoal, Pencils, And Pastels! Save yourself and your fingertips from the dirt of blending charcoal, pencils, and pastels by hand. Prevent oily hand residue from finger blending and use Creative Mark's Blending Stumps instead! These traditional double-ended blenders are manufactured from soft paper felt and make short work of blending. You can easily clean the stump by sharpening dirty portions off on a sanding block. These blending stumps make for great gifts for black and white artists, charcoal and pastel designers, and any level of artist using tortillions and blending stumps!
