Blend to your heart’s content with the Tortillon Set of 3. Made of tightly wound, fibrous paper sanded to a point, tortillions are used to smudge and blend when drawing, usually in charcoal, graphite, or pastel. This avoids blending with the finger which can leave oils on the drawing surface. The fine tips are ideal for working with detail. Keep the tip clean and sharp by sanding it. If you just want to clean it, try using an eraser. This set of tortillons contains a Small (6 mm × 70 mm), Medium (7 mm × 80 mm) and a Large (8 mm × 90 mm).
