The Mason Pearson Pocket Bristle & Nylon brush combines boar bristle clusters and nylon strands with a dark ruby handle, forming an elegant and time-tested brush. Hand-finished with Mason Pearson's original 1885 design, this brush strengthens and protects the hair by coating each strand in the sebum that naturally resides at the root. The brush also features a rubber cushion pad that massages the scalp. The Pocket Bristle & Nylon measures 6. 75 x 2 .
