Faber-Castell white moldable rubber The malleable rubber is ideal for correcting drawings made with pencil, charcoal or pastel. It is also useful for blurring strokes in drawings made with these techniques. It is easily molded, allowing you to give it the shape you want. Generates a minimum amount of waste. It should be noted that it traps the chips present in the case, so it is recommended to store it in a separate box or bag. Brand: Faber-Castell.
