Factis Kneadable Eraser
Factis Kneadable Eraser is a very soft kneadable eraser that removes and blends all charcoal, pastel and pencil drawings and sketches without bruising the drawing surface. Being pliable makes a putty eraser particularly useful for erasing small areas as you can shape it into a point, creating highlights or performing detailing work. Putty rubbers are commonly used to remove light charcoal or graphite marks and in subtractive drawing techniques. They are ill-suited for completely erasing large areas, and may smear or stick if too warm.
