Just the quick review of two of my very good customers (for badger hair brushes!!) about their experience with the Muhle STF 25 mm knots:
"Dear Rudy : recieved brush just a few minutes ago. I have a dumb question. The muhle STF is synthetic right ? I'm just absolutely pleased with the brush being synthetic. Never have I felt a synthetic like this knot.
Best regards. Ray S"
"and others, ended up selling them all because they did not emulate a badger enough, which I know is not what some people want.
This Muhle STF is the closest I have ever used, it loads and releases lather easily, it splays like a badger and can hold enough lather for 4 passes and have enough left to cover my face while I clean up my gear."
