ABSTRACT:
An improved mascara brush has a typical twisted wire core containing bristles having a double lumen cross-section. The bristles are generally circular in shape, and hollow, with a dividing web across the midpoint of the bristle, thereby defining two longitudinal lumens extending along the length of the bristle. In other embodiments, the bristle is oval, square, rectangular or another polygonal shape.
