A mascara brush with a core comprising at least two sections of wire twisted together along a wire core longitudinal axis and a set of bristles comprising bristles of plastic formed by filaments, which are respectively clamped between the two sections of wire and are formed at their free ends with a wedge-shaped bristle tip or without a wedge-shaped bristle tip. The mascara brush provides an increased storage capacity for the mascara composition to be applied with improved delivery of stored mascara composition to the lashes. This is achieved by the bristles being formed from a plastic material extruded into a fibre, to which outwardly protruding particles are added and/or which is provided with punctiform depressions (indentations), which roughen the bristle surface, wherein the bristles that have a wedge-shaped bristle tip at their free ends comprise at least one cut surface that forms a wedge and the surface roughness of which lies between 0.2 μm and 6.3 μm, in particular between 2.9 μm and 6.3 μm.
