Abstract
An improved mascara brush has a typical twisted wire core containing bristles of Z-Shaped cross-section. The Z-shaped cross-section may be a conventional Z-shape; or it may be square or rectangular thereby defining a cross-section of discontinuous square, diamond or polygon shape with a connecting web; or it may be circular or oval thereby defining a cross-section of discontinuous circular shape with a connecting web. In either embodiment the cross-sectional shape effectively creates two longitudinal voids extending along the length of the bristle.
