This is not a review about the knobs but is a review of failed customer service. The knobs themselves are wonderful, but I ordered green and was sent brown. The first 3 phone calls to report the error in sending the WRONG colored knobs, I was again sent the wrong color (brown again). So I reported the error again, The third set of knobs also came back brown. The solution is to order directly from the artist himself.

High quality and fun to mix ‘n match.
