This is a ReFa hairdryer, manufactured in 2021. I've used it for about 2-3 years, and it has been confirmed to be working without any problems. I'm selling it because I bought a new hairdryer. I've wiped down the visible parts (exterior) with alcohol, but the internal dust remains as it is due to the non-disassemble structure. Thank you for your understanding. It has been used to a certain extent, so please refrain from purchasing if you are concerned. The included item is the warranty. *It will be shipped without the box.
