da Vinci varnish & priming mottler brush with extra short hog bristle and natural lacquered handle is made for the demands of oil and acrylic painting. Professional quality hog bristle produces a controlled stiff stroke which is great for blocking out large areas of paint. The bristle is set by hand, not cut therefore brush retains its natural flags or split ends for even paint distribution. This series is ideal for priming, gesso, underpainting, varnishing, graining and transparent painting with great control.
