The 971 Slanted Double Dome Blender brush is a unique double dome brush that allows for quick and effortless application and blending. It functions as a two-in one, multi-tasking brush so 1) you donâ€t need to hold multiple brushes in one hand, and 2) your kit stays lighter and less bulky. It consists of both a small and large dome. The small dome has a matte surface with micro wavy bristles that picks up more product for a thicker application. In contrast, the large dome has a shiny surface with straight bristles that picks up less product for a more lightweight and natural application. Apply foundation using the longer, flat side of the brush. Then, use the shorter side to diffuse and soften the foundation. The slanted design of this brush allows for a more precise application of the product in curved, creased, or deepened areas of the face and body.
