The CSS Series 1135 varnish brush is made of fine light Ox hair. This is a good all purpose brush that can be used for varnishing, cleaning, applying gilders clay and much more. The hair length out on the brush is slightly shorter than a standard varnish brush. The 2" brush has hair that is 1/4" inch thick out of the ferrule, is 1-3/8" in length and hand cupped to a chiseled edge. The hair is set in a nickel plated ferrule on a 6" black lacquered handle.
