While this is a beautiful knob and I loved it when I saw it on my new bathroom vanity when I pulled out the second one to put it on I felt the back of the knob that goes against the vanity had a metal bump on it. Upon further inspection it I realized it protruded quite a bit and I was afraid it would ruin the wooden drawer. I looked at the first one I had put on and there was a hole in my brand new wooden vanity. NOT HAPPY!! None of the 6 I purchased had this metal burr or whatever it is taken off. They should not have this metal protrusion to damage furniture. I am returning.
