I picked these up from the Bay and am fairly certain they're legitimate. The hair is what i consider to be the 'Rooney' hair with strong dense shafts, which is somewhat different than the Simpson Best hair, which isn't quite as sprite.
I thought my SBAD was over and i was wrong so here we go.
Each of these are fantastic brushes, made by hand, and have some pretty serious heft to them. They've only been used a couple of times each and have not shed a hair.
