The 10mm-nap version of our mini rollers also comes in a 100mm length. This particular roller holds a considerable amount of paint, washes out easily, and is ideal to cut walls and ceilings in conjunction with our 10mm-nap big rollers, as doing so will result in a uniform finish with no picture framing. Perfect for use on radiators, exterior weatherboards, and previously painted surfaces, these mini rollers eliminate the need to lay off your paint.
