ionac Shower Head Unused main unit + 1 replacement filter set. I bought it for my stay abroad and took it with me, but I didn't use it because it wasn't a hard water area. I took it out of the box and wrapped it in bubble wrap, so the instruction manual is slightly creased, but it's unused. All adapters and packing materials listed in the instruction manual are included. Please ask if you have any questions. Although it is unused, please understand that it has been stored at home before purchasing.
