Fill the bottle-like handle on these rollers with paint and dispense as you roll, so you don't have to stop at a paint tray. Rollers are short for quick touch-up jobs or to fit in tight spaces. Rollers have a woven fabric nap that leaves a smooth finish. Use them with latex and other water-based paint on smooth and semi-smooth surfaces, such as metal doors, cabinetry, walls, and ceilings. The handles come with a cap so you can keep paint fresh between jobs.
