"This is a distinctive brush made of five diameters and three lengths of an exclusive Polymide filament. Each strand is tapered to a precise tip, much like natural hair. The combination of multiple diameters and lengths allows for the formation of color-carrying pockets within the brush. The tapered tips make this the best-pointing synthetic available, especially in the larger sizes. The striking look of this brush, combined with the same craftsmanship built into all of our Master Series bushes, makes it a pleasure to use. Lifetime Guarantee — When properly used and properly cared for, Blick Master Series brushes will last a lifetime. If at any time you are dissatisfied with the materials or performance of a Master Series brush, you may return it to Blick for a replacement. Note — These brushes may have either a silvertone or goldtone ferrule." -Blick

This brush is made with synthetic fibers that are specifically designed to perform like natural hairs or fibers.
