Please be sure to read the profile before purchasing. Takagi Shower Head with Water Purifier Water purifier part (for ■JA3-03) JH030JA3MLG Used for about 2 and a half years. There are some scratches and limescale stains, but it's relatively clean, so I think you can still use it. Home cleaned with citric acid. Cartridge not included. Instruction manual is not included, please refer to the images. It has a function to prevent forgetting to insert the cartridge, so you cannot switch to purified water if the cartridge is not inserted. *For used items, only for those who understand. *Please refrain from purchasing if you are sensitive to details. Thank you.
