Size: 175x10 mm; Material: steel wire; The metal brush has a steel bristle in a plastic case and a convenient plastic handle. It is used for cleaning metal surfaces, and is also great for cleaning cliches made of brass and steel for hot stamping. Especially the brush is needed for cliches for branding buns and applying images to rubber. Also it will be usefull in places, where particles of the substance stick to the cliche and the application of the next print is impossible without cleaning it from previous use. PRC
