Keep your hats looking new with M&F Crown Brushes.  We recommend using the black brim brush on black felt hats, and the light grey brush on light color felt hats. Made with 100% horsehair. Designed for getting that extra dirt and grim out of your felt hats after long days at work or from getting your hat out of storage. Tough enough to get the dirt off, but gentle enough to give your hat a polished look.
