The Proraso Shaving Brush is made of natural bristle. This slick, professional brush which is slightly bigger than many other brushes on the market, will give you that edge for a professional shave. The natural hairs feel good on the skin and the large grip makes the brush nice and easy to handle. Their length and stiffness have been specially designed to encourage the best soapy lather and to delicately, yet energetically massage the beard.
