The Angle Chisel Fluff Brush is designed to apply eye shadow perfectly along the under side of the orbital bone or the crease in order to contour the eyes for beautiful strength and lift . It works best to start at the outer edge of the eye, using short feather strokes moving in toward the bridge of the nose. Examples of really great eye shadows for this effect are Bronze, Bamboo, Cornerstone, Flame, Eve, and Whisper.
