Finest quality professional grade 9" Microfiber roller covers. These rollers allow for maximum pickup and loading of many paint applications. When compared with general use polyester roller naps, microfiber not only holds more of the paint application, but it also releases the application better onto the surface, providing the benefit of not having to load the roller nap as often. Another benefit of using microfiber is the smooth, sleek shed-resistant finish it provides. The core is made of a dense polypropylene. Recommended for use with stains, latex paints, enamels or acrylics.
