With the Bosch contour sanding sponge set, you can smoothly finish curved surfaces, shaped profiles, and hard-to-reach edges with complete control. Unlike conventional sandpaper that creases or tears on rounded contours, these flexible 120 x 98 x 13 mm sponges adapt directly to the shape of the workpiece for even pressure distribution. This makes them ideal for preparing wood and metal surfaces, smoothing armrests and baseboards, or scuffing between coats of paint. The 3-piece set provides a complete range with medium, fine, and superfine grades. Thanks to the clear colour-coded system, you can instantly select the right sponge for dry or wet sanding applications.
