The Mason Pearson Universal Military Nylon Hair Brush has 7 rings of nylon tufts set in a pneumatic rubber cushion. Cleaning brush included. Mason Pearson has established a unique reputation for hair brushes. The reason for this is partly in the design and partly in the versatility of the brushes. The design consists of unique spired tufts of boar bristle, or nylon, or bristle-and-nylon mixture, set in a pneumatic pad so that every tuft penetrates right through to the scalp. In addition, the materials are first-class. With the range of materials, sizes and colors offered, there is a Mason Pearson for every type of hair.
