These high quality brushes are made of tapered white Taklon fibers that are designed to have greater resiliency and to hold a consistent point. Taklon is a synthetic fiber that is pure white in color and will stand up to use that would make a natural hair brush fall apart. This is a great brush for spot testing of color sensitive materials. The Taklon fibers stand up to use with strong solvents quite well. The black lacquered handles are approx. 8" in length and have seamless nickel plated brass ferrules.
