Natural bristle is stiffer than horse hair and goat hair, but being a natural material remains gentle and forgiving on the skin. Its excellent brushing characteristics make this brush very good for general grooming. This version comes in a case of four, with one each of the following color combinations, blue/green, blue/red, blue/yellow and red/green. At the time of writing there is no one else in the industry that is able to offer dyed bristle. See also B1447 and B1595.
