The Pro Arte Series A Oil Colour Brushes are fine quality hog tools are made from Jyukeis hog - the highest grade of Chinese bristle presently obtainable and considered by connoisseurs to be without equal. The bristle is extremely firm and, in the case of the Long and Short Flats, incurves to a beautiful razor’s edge, imparting much spring and being highly responsive to oil paint. However, their greatest virtue of all is in their ability to maintain good shape even after many hours of continuous use and cleaning. There are four shapes of brushes in this range; Round, Filbert, Short Flat and Long Flat. Seamless nickelled brass ferrules. Long green polished handles.
