The Eco Tools Microblending Brush is designed with steep angled bristles for precise blurring under eyes & in hard-to-reach areas. Dab flat side of brush in your favourite concealer. Gently apply product in a “V” shape starting under the inner corner of your eye & ending at the outer corner. Blend in color using short, light strokes for a soft, airbrushed look. TIP! This brush works great as a shadow blending brush.
