The Umbria line of brushes is truly special with its deep olive-colored handles coated with Princeton's Velvetouch silicone finish. This short-handled brush works well with gouache but is best for use with medium or heavier viscosity paints. A favorite of decorative painters, Umbria also excels with all acrylics. Liners are similar to rounds, but with longer hairs. Liners have a large color carrying capacity and make long, fluid strokes.
