110 ml leather masking rubber. Rubber with a design that can be laminated once dry to create reserve areas in leather or synthetic leather, for drawing or writing. Application in thick layers. The drying time varies according to the thickness applied, about 30 minutes (possibility of accelerating drying with a hair dryer). The bluish color makes it easy to identify reserve areas; it darkens when drying. It is possible to apply it directly on the substrate and then apply the color to it, once the gum has dried, or to draw with an eraser on a color already applied and to cover the masking eraser with another color to have a color reserve area and not the support uncovered. Once dry, the rubber simply peels off with your fingers by rubbing and within a maximum of 15 days from its application. To obtain clean lines after rolling, it is advisable to apply a thin layer of color on the previously dried gum. The brush can be cleaned with water and soap.
