3-piece round Red Sable brush set by Atlas Brush. Red Sable is ideal for all oil based paint including Billing Boat paints. Also works well in lacquers, polyurethanes, and other non-water based paints. They can be used with water-based paint but this is not the best choice as the water can swell and distort the bristles. Nice all purpose set for fine lines, featuring sizes: 10/0 (0000000000) super fine, Size 5/0 (00000), and Size 0 brushes. Ideal for hobby, artist, and craft uses. Natural Red Sable Bristles, aluminum (non-rust) ferrule, lacquered wood handle.
