The Kolinsky red sable used in the construction of these brushes is the highest grade of red sable hair from the Tobol and Ussuri river regions in Siberia. Expertly shaped, these brushes are unmatched for spring, resiliency, color and water carrying capacity and their ability to hold a sharp point. They are excellent for precise, controlled brush strokes, detail work, illustration and restoration. Each brush features a durable, seamless, gold-plated brass ferrule and a beautiful anthracite transparent lacquered handle.
