[0002] Roller brush, also known as roller, is divided into three types: long-hair, medium-hair and short-hair. It is a tool used for rolling paint on large areas. Roller brushes are often used when rolling paint on large areas in daily architectural decoration projects. Roller brushes need to be used with a paint tray. Due to their wide rolling range, they are the most labor-saving and time-saving brushes, especially when connected to an extension rod, they can easily paint high walls or ceilings.
