Sold separately by style or complete set. Princeton’s new series of synthetic hair brushes features an extra degree of stiffness to move and control color. The bristles on these brushes will retain their shape and stiffness much longer than most other brushes on the market. Each brush features two shades of hair, seamless gold colored ferrules, and a Velvetouch handle for excellent grip and control. They can be used with heavier acrylic paints as well as oil and water based oil colors.
