ABSTRACT:
A brush (200) has a straight stem (201) defining a main axis (X-X), a flexible core (202) having a first end integral with the stem and bristles (204) implanted radially in the core. The ends of the bristles define the surface (205) of the brush, this surface having a first face. The intersection of any meridian plane passing through the main axis with the surface of the brush defines two peak lines (207) having a specific curvature. The core is curved, the peak lines (207) are concave and the first face (207.1) is substantially straight and parallel to the main axis (X-X).
