Able to cut a sharp line even in hot or humid conditions, Ultra/Pro Extra-Firm is the perfect choice for all thick or fast-drying paints and primers. It excels during exterior use. Made from 100% nylon and featuring an exclusive Wooster filament called NylonPlus, it maintains rigidity, resists wear, and cleans much more easily than brushes that use polyester to achieve extra stiffness.
