The original synthetic artist's paint brush, The Robert Simmons White Sable brush was developed in the 1970's to offer a synthetic watercolor brush that could compete with the increasingly expensive Kolinsky Red Sable brushes. Made from different thicknesses of synthetic filaments, it can hold large amounts of color and has excellent snap and spring. Seamless nickel plated brass ferrules are attached to handles of beechwood from the forests of Maine. 15 shapes and sizes to choose from.
