The present invention relates to an device for applying a flowing or paste-like product to keratin fibers, comprising an elongate central core (1) extending along a longitudinal axis XX, at least one row of elongate bristles (2) comprising a first end (20) embedded on the core and a second, free end (21), the bristles (2) and the core (1) being made in one piece. According to the invention, at least one of bristles has a flattened shape in a plane substantially perpendicular to axis XX, said at least one bristle being defined in a front view by a first ridge (25) that is continuously convex or concave from the base (20) thereof embedded in the core (1) up to the second end (21), and by a second ridge (26) consecutively concave and convex from the base (20) thereof embedded in the core up to the second end (21), the first and second ridges meeting at the free end (21). The bristles have a slit (24) in the body thereof for defining a first (22) and a second (23) side flank arranged opposite one another. Two bristles consecutively rooted along the length of the applicator may form at least one distal opening (30) between one another.
A device for applying a product of fluid or past-like type to keratin fibres, comprising an elongate shaped central core that extends along a longitudinal axis XX, at least one row of elongate bristles comprising a first end embedded on the core and a second free end, the bristles and the core being formed in a single piece, characterised in that at least one of the bristles has a flattened shape in a plane substantially perpendicular to the axis XX, said at least one bristle being defined in front view by a first ridge continuously convex or concave from its base embedded in the core to the second end, and by a second ridge having at least two curvatures separated by a change-of-direction point from its base embedded in the core to the second end, the first and second ridges joining at the free end, and in that said bristles have a slot in their thickness able to define a first and a second lateral flank disposed facing each other.
