Authentic ReFa FINE BUBBLE ONE, unused. I purchased it about a year or two ago, but when I tried to install it, it turned out to be incompatible with my shower's specifications, so I couldn't. I have kept it stored at home since then. Included items: Shower head body, box, warranty card, serial number card, booklets x 2, adapters x 3, adapter cover, packing x 2 Although it is unused, it has been stored at home, so please understand that there may be minor scratches or dirt. Thank you for your understanding.
