Our #18 HD Face Contour Detail Brush  easily glides under the cheekbone and with the hollow of the cheek, creating a very dramatic and linear contour application. The soft bristles blend and disperse the product without losing their compact shape, leaving you in total control over product application. It is also the perfect tool for baking and cleaning up contour lines due to its flat surface and its ability to pick up large amounts of loose setting powders.
