Abstract
In a mascara brush comprising a plurality of bristles retained between two intertwisted wire sections, the bristles being trimmed to define the contour of the brush, it is provided, with a view to obtaining clearly improved handling and combing properties, that the bristles are trimmed so that on the one hand, seen in a cross-section, they are asymmetric in such a way that the bristles have a shorter extension from the intertwisted wire sections towards one side while having a longer extension towards the other side, and that on the other hand, seen in a longitudinal section, the bristles are also trimmed asymmetrically in such a way that they have varying lengths.
