Eyeshadow aficionados know the struggle of blending and buffing harsh demarcation lines. When you want a seamless transition between darker and lighter colors, you have to blend and buff, and buff and blend, and buff some more, and then blend some more. A harsh line of demarcation can really derail your eye look. Sigma Beauty’s Max Blending Brushes bring the blending A-game to your routine. You get the E25 Max Blending Brush, which sweeps color across the lid. The E40 Max Tapered Blending Brush softens and blends color, while the E45 Small Tapered Blending allows you to buff that crease. The E49 Medium Tapered Blending is specifically designed for transition shades. So this kit is basically ALL the tools you need.
