Select the dark bristled brush for use on darker shade felts. Brush the hat in a counter-clockwise direction, against the lay of the nap, so that the felt is worked well and dust is best removed. This is also a great clothes brush. Reserving one for light colors and another for dark avoids the transfer of hat dye from dark to light felts and vice versa. Available to order with your logo. 36 piece minimum. Contact us for information.
