The Wooster 9" Candy Stripe 1/4" Nap Roller Cover is a specialized roller cover used to apply smooth coatings such as varnishes, enamels, and urethane. The "Candy Stripe" refers to the roller cover's alternating blue and white stripes, which help to uniformly distribute the paint on the surface. With a 1/4" nap, this roller cover is ideal for smooth surfaces requiring a thinner coat of paint, such as trim work, doors, and cabinets. It offers exceptional control and easy application, allowing you to produce a faultless finish on your projects.
