Mascara brush
A mascara brush serves to apply a mascara mass onto the eyelashes. It comprises a plurality of bristles that are secured between two twisted wire segments and extend out from the wire segments. The free ends of the bristles are tapered wedge-shaped in cross section. This serves to improve the combing result of the mascara brush.
