Linzer ProEdge Microfiber Mini Paint Rollers hold three times the paint or stain than foam rollers, made from a shed-resistant fabric that produces a minimum of splatter on smooth and semi-smooth surfaces. They're ideal for low-VOC (Volatile Organic Compound) paints and all sheens. They can also be used with latex paints. The roller is 4" wide and includes a frame and handle. The refill pack includes two roller sleeves.
