ABSTRACT:
Improved paint brush bristles formed of synthetic materials are hollow and tapered with a central axial hollow. The tapered hollow bristles are characterized by their consistent wall thickness, i.e., ratio of cross-sectional hollow area to cross-sectional wall area remains consistent from one end of the bristle to the other; and by their consistency in neck-down location.
