The Pro Crease Detail Brush is designed for adding detail and intensity to eyeshadow looks. Because of its small compact size and sable/squirrel blend of bristles, the Pro Crease Detail Brush easily adds a smokey effect by packing on the powder where desired. Use on the outer crease of the eye to add intensity and depth to any look, or use to blend product into the bottom lash line to create an even more finished overall shadow application.
