I purchased this about two years ago, but I've only used it about 10 times? I used it when I shampooed. Afterwards, I washed it thoroughly and stored it at home. I've confirmed that it works. It comes with the box and instruction manual. From what I can see, I think there are no major scratches or stains. Please understand that it has been used once. Retail price: I bought it for 10,780 yen.
