If you wanted to grow a beard while serving under Alexander the Great (356-323 BC), you'd be S.O.L. Before each battle, he insisted that all his soldiers be shaved. They would never have had the chance to enjoy this Military Style, 100% pure boar hair beard brush. They'd never have felt the extra-soft bristles exfoliate and stimulate their beard skin. Beard oil would drip from their chin rather than being evenly distributed throughout their beard. Fortunate for you, service under Alexander the Great is not an option and you can enjoy the benefits of this beautiful brush.
