Contour Makeup BrushI recommend this contouring brush if a more diffused finish is desired. Just apply contour color to the flat part of the brush, rotate the brush upside down so the flat edge is facing up and apply color in the crease using a horseshoe shape motion. This is the best brush for opening up the eye area. If you need extra help just call us and we'll walk you through. To clean brush use mild shampoo and warm water.
