Zenith Pro Aluminum Handle Boar Shave Brush. 26x64mm Knot B1
Metal Handle Professional Shave Brush. This brush has a large and dense 26 mm Boar Knot attached to it. This is the standard size for the Zenith Pro brushes, loft is set at 64mm. Effective loft is 58-61mm from glue bump. Total weight is a respectable 94 grams.
In one picture, I've shown a used Omega 48 for comparison. It is very similar in size. While the handle is longer, the actual knot height is the same. The perceived knot height will be less because of how the Pandolfo artisans epoxy the knots.
