"Every Blick Master Natural Pure Squirrel Brush is crafted of pure Kazan Squirrel, formed by hand by the same craftsmen who produce our finest Master Sable brushes. A more affordable hair than Sable, Squirrel has excellent capacity and a tendency to release paint to the surface with more immediacy. We then take it to the next level by giving each brush a "shape-memory" — resulting in a brush that points well the first time you wet it and remembers its shape every time you use it.

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
