Utility Mineral Makeup Brush. Small makeup brush for hard-to-reach areas. The Utility Mineral Makeup Brush is specifically designed to apply the Pür Minerals 4-in-1 Pressed Mineral Makeup Foundation to those small and hard-to-reach areas. The Utility Makeup Brush effectively masks under-eye circles, broken capillaries and blemishes with superior coverage. Made of all-natural, cruelty-free goat, sable and pony hair, the Utility Makeup Brush feels soft against your skin and helps you achieve a flawless finish. It’s great to be used as a concealer brush or crease brush and in a pinch, it can also double as an eye shadow brush.
