The definition of a classic, you'll use this cult-favourite, fluffy SigmaTech fiber brush every day for eyeshadow application and blending. Our E40 Tapered Blending Brush is best used for softening harsh lines or applying a transition colour to the crease. The E40 soft brush head will gently apply colour, ideal for placing highlight products on the brow bone. Recommended Use: Using just the tip to apply colour, sweep back and forth through the crease for a diffused and blended finish.
