The Chisel Shadow brush is a double-ended favorite because with a simple flick of the brush you can swap the style of application from a soft powder line (or wet powder chisel line) and fade or intensify with the round end.

Cleaning and Care: The chisel end is made of Taklon, the shadow end is made of animal hair both are easy to clean with your own shampoo.  Rinse well, press out water, put into shape and leave to air dry.
