摘要： A cosmetic brush and a process of making same. The brush comprises a substantially longitudinal stem and a plurality of bristles, each bristle extending from a base associated with the stem and terminating with a free end, each bristle having external walls and a longitudinal axis, the brush further having a major axis disposed along the stem, wherein the plurality of bristles comprises selected bristles, each of the selected bristles having at least one external depression oriented in a direction substantially parallel to the longitudinal axis of the selected bristle. The process comprises the steps of forming a hollow stem from a first moldable material; providing a plurality of bristle-forming channels surrounding and abutting the hollow stem, each of the bristle-forming channels, the plurality of bristle-forming channels comprising selected bristle-forming channels having at least one protuberance; injecting a second moldable material into the hollow stem under pressure sufficient to rapture the hollow stem in predetermined locations corresponding to the bristle-forming channels and to fill the bristle-forming channels with the second moldable material; and solidifying the second moldable material.
