Shop 170 Synthetic Rounded Slant Brush online at Bloomingdales.com. Its round and slightly domed, slanted shape--paired with densely packed, luxuriously soft synthetic fibres--make this brush ideal for applying, buffing out and blending thick creams and liquids with a smooth, even finish. Works especially well with M·A·C Studio Tech. M·A·C professional brushes are hand-sculpted and assembled using the finest quality materials. They feature wood handles with nickel-plated brass ferrules.
