This brush is for pristine application power for powder, liquid, or cream products. It blends eye shadow & pencil with ease. Bdellium Tools Maestro series brushes are hand-crafted beauty tools made of first-rate superior quality material. The Maestro series is a more luxurious professional grade line of tools. The major difference between the Maestro series and the Studio line is the handle color and the material used for the ferrule, which is more shiny, durable and stronger than the anodized aluminum ferrule used in the Studio Line. All of the Maestro series brushes are treated with an antibacterial agent on the bristles.
