The Semogue 610 Black Extra Boar Bristle Shaving Brush looks amazing with its black and clear handle and natural boar bristles. These superior bristles are renowned for their stiffness, meaning a great exfoliation before your shave. Note that these bristles will soften with time and use. As with all Semogue brushes this model features the renowned metal ring, a trademark and a reinforcement to keep the bristles in place.
