This workable paste gum is used to erase charcoal, graphite pencil, pastel, sanguine ... It absorbs pigments that are deposited excessively on paper. Just squeeze it to clean it, and to be able to erase again effectively. It has the advantage of not leaving flakes on the surface. Thanks to its flexibility, it lets you create pointed shapes to erase very fine parts or a ball or flat shape to clear larger sections of a drawing, and erase more or less according to the pressure exerted on the drawing. After a while, it becomes completely coloured, and it must be changed to prevent leaving marks on the paper.
