4" long roller cover with 1/2" Nap. Shed-resistant and high-capacity for today’s paints: flat, eggshell, satin. HydroFlow technology provides controlled release to improve paint flow.
Much better than the tray that Purdy offers, it doesn't have those huge channels on the side for paint to get lost in. Also, it is sloped properly, don't have to prop the back end up like I was doing with the Purdy to get all the paint down wear my roller could hit it
