This abrader is similar to the 2mm and 4mm glass fibre propelling pencils we sell, but designed for use if you are working on larger areas. It is 10mm in diameter, 180mm long and string bound. As the fibres get worn, the string can be unwound and cut off a little at a time, leaving the fibres long for a softer polishing action or keeping them short for a more abrasive action.
