Princeton Series 6150 Brushes feature soft white nylon hair, hold an ample amount of color, and are very responsive. They are ideal for both amateurs and professionals working with watercolor applications. Unlike many nylon hair brushes, the hairs on these brushes are interlocked, producing a strong point that retains its shape after repeated use. Each brush comes equipped with a short, hardwood handle and a seamless, nickel-plated ferrule. Experience Princeton quality and value and see for yourself why so many artists choose Princeton as their source for brushes.
