The at least one tuft comprises at least one filament having a longitudinal axis and a non-circular cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The at least one filament is bent around the anchor so that a first limb and a second limb extend from the bristle carrier. The first limb comprises a first free end, and the second limb comprises a second free end. Each free end is twisted around the longitudinal axis by a twisting angle a of about 80° to about 100° , preferably about 90°.
