Grundy’s Finest Finishing Brush is made of soft dense black horsehair which remove light dirt, sand, dandruff, and dust with just a few strokes.
The handles are incorporated in a resin material back w/o the use of any glue or tack. The brushes can we washed with a mild soap and air dried (not in the sun or a heater). Haas recommends Mattes lambswool wash or Pepede.
