A 30 mm Boar knot is like a Land Cruiser, after 400 000 km it is nicely run in and will carry a load as big as you can imagine without breaking a sweat. This one fitted to a Knysna Yellowwood knot that has some light grooving on the top part.
The brush stands 126 mm tall, with the loft at 66 mm. The waist is 30 mm and the collar around 40. The brush weighs 79 grams.
