They're amazing, and getting better ever time I use them. I had no idea what to expect, and I'm blown away. The 26mm is Manchurian Silvertip, and the 40mm is Finest... I've never really looked forward to using a brush before - now I get it.
How are they with shedding? I understand an initial loss of a few as long as it settles down. I'm thinking of purchasing a few of his knots for my personal brush collect and not for resale.
