Silver Tip brushes are made the Wooster way, using our exclusive formula of CT (chemically tipped) polyester. This filament is verythin, flexible, and soft to virtually eliminate brush marks. Silver Tip brushes have excellent leveling and smoothing properties with all paints, but are especially suited for applying enamels to metal, varnish or polyurethane on wood, and lighter or thinner water-based coatings. The Wooster Brush Company has been manufacturing innovative, high-performance painting tools right out of Wooster,Ohio USA since 1851. You can feel confident knowing Wooster is the name behind your painting tools.
