ReFa DUO ReFa DUO ReFa x dinos Collaboration Product dinos Limited ReFa DUO I purchased this on August 25th of last year, so it's still within the 1-year warranty period and I have the warranty card. However, I cannot fill in my name and address on it. Please understand. m(_ _)m I used it about 10 times after purchase and then stored it. I have not used it in the bath. There are no noticeable scratches. Please only purchase if you understand that this is a used item. Please refrain from purchasing if you are sensitive to such things. Thank you very much.
