This is a nearly new (used only 6 times) Muhle Silvertip Fibre (STF) brush in the largest size (25mm). It is by far the best synthetic knot I have used, including the high end Simpsons Duke and Chubby Platinum synthetic brushes. I am selling it because the handle is a bit small and difficult for me to hold with my arthritic fingers. Folks with "normal" fingers should not have any problems. My wife tried it and thought it was just fine. It is currently selling new on Amazon for $86; I am asking $60 shipped CONUS. I will ship overseas if you are willing to pay the postage.
