RUBY SATIN: Each brush in our Ruby Satin line is designed with 5 diamond superior stiffer multi-diameter synthetic filaments that imitate the firm snapback and holding capacity of mongoose hair. They are durable and firm enough to carry heavy bodied paints 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. These brushes can be used on canvas, substrate, metal, leather, paper, panels, boards and on smooth and textured surfaces. They can also be used for face and body painting. Each brush has an olive green wooden handle that is finished with a sophisticated nickel-plated brass ferrule.
