Alpha is made with a one-of-a-kind filament blend. It offers the smoothest flow (less drag) and carries more paint at the end of the brush, so it releases evenly to the surface less effort while painting. In fact, Alpha paints up to 30% farther per dip compared to other brushes of equal size! Alpha features Micro Tip technology that delivers a finer finish than any other brush on the market today. It is designed with more fullness at the end, but still has Wooster's cut-in ability. Proven by contractors in the field and testing in the lab, Alpha is the leader in overall production efficiency.Alpha™ Professional Angled Cut Sash Paint Brush, 2-1/2 x 5/8 Inch, 2-15/16 Inch Synthetic Bristle, 7-7/8 Inch L Handle
