Alpha is made with a one-of-a-kind filament blend. Designed to carry more paint at the end of the brush, it releases evenly to the surface for less effort while painting. Alpha features Micro Tip technology that delivers a finer finish than any other brush on themarket today. It offers the smoothest flow (less drag), and also cleans quickly when the job is done. The brush is fuller at the end, but still has Wooster's cut-in superiority to control paint and produce the sharpest lines. Proven by contractors in the field and testing in the lab, Alpha is the leader in overall production efficiency.
