Camel-hair brush
A camel-hair brush is a type of paintbrush with soft bristles made from natural hairs, usually squirrel. Camel hair is not a suitable material, although historically camel was used for ancient Chinese ink brushes (and for camel hair cloth). It is a widely used brush in art, but is considered inferior to the more expensive sable and ox-hair brushes. In some niche applications, such as pinstriping, camel hair is an ideal brush. Camel-hair brushes have numerous uses outside of art, particularly dusting where a soft brush is needed for delicate objects or skin.
