Paint-Brush 3" XFirm

These brushes feature an extra-firm blend with a strong touch. Made with a combination of purple NylonPlus (a new generation of nylon filament) and purple and black nylon. They provide unbeatable performance wherever a stiffer brush is needed. Great for all thick, heavy coatings such as exterior paints. Maintains a sharp edge - even in hot, humid conditions. Carries more paint to the wall and cleans up fast when done. The Lindbeck treated maple wood handle has a round rust-resistant steel ferrule. Its long and uniform thickness allows the painter to easily turn the brush and reach into corners.No. 4153-1-1/2: 1-1/2" W. x 2-7/16" L. x 1/2" thick bristlesNo. 4153-2: 2" W. x 2-11/16" L. x 9/16" thick bristlesNo. 4153-2-1/2: 2-1/2" W. x 2-15/16" L. x 5/8" thick bristlesNo. 4153-3: 3" W. x 2-3/16" L. x 11/16" thick bristles
