I wore these sunglasses maybe one or two times and kept them in storage in my sunglass box they are authentic. They are in almost new condition. However, there is green oxidation showing on the sunglasses. I googled this and it seems to be normal, but I haven't tried to remove it, price reflects the green oxidation!
