A polymer bristle (100) for a liquid-applying brush such as a paint brush includes in cross section a central bore (95), an annulus (96) and preferably three radiating spokes (97) with parallel sides and rounded tips. The bristle is tapered from a thick end (101) that is bundled into the ferrule of a brush toward a thin end (103). The bristle may be flagged by slits (130). |
