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. FILBERT COMB BRUSH: Filbert grass combs are superior tools to use when creating paintings with lots of texture. Paint portraits filled with hair, fur, grass, and other unique, textured designs. The short handle is ideal for tabletop painting. PAINTS: Each Ruby Satin synthetic brush can be paired with heavy-bodied acrylic or oil paint. These professional paint brushes also work well with fluid and flow acrylics, proving they are extremely versatile. Enjoy the smooth, colorful strokes.
