Big Scrubby Zenith Pro Aluminum Handle XL Boar Shave Brush. 28x50mm knot. B14I am so excited about this one. I special ordered a short version of the pro version with a large knot. I had them made without the nickel ring on it so that they could put a larger (28mm) knot in it. It is supposed to be a larger version of the B03 A26 brush that I've been recommending for face lathering but with an even shorter loft. This is a very short brush for a boar knot this size. The effective loft is 43 46mm with glue bump. Metal Handle
