RUBY SATIN: Each brush in our Ruby Satin line is designed with synthetic fiber tips that imitate the firm snapback and holding capacity of mongoose hair. They are durable and firm enough to carry heavy liquids yet make smooth strokes. MATERIALS: Our Ruby Satin professional artist brushes are expertly crafted with synthetic mongoose filament and are fit for rough painting surfaces. Each brush has a wooden handle that is finished with a sophisticated, nickel-plated brass ferrule. ROUND ARTIST BRUSHES: Our round art brushes are superior tools to use when creating precise, detailed work. Each round brush can create thin lines and broad strokes. The short wooden handle is ideal for tabletop painting. PAINTS: Each Ruby Satin synthetic brush can be paired with heavy-bodied acrylic or oil paint.
