I am selling this item because it is no longer needed due to a move. It is a Cleansui square pot-type water purifier. It is a set with three unopened water purification filters. (Includes instructions on how to replace the cartridge.) One filter lasts for approximately three months. There are some minor scratches on the surface of the pot, although they are not very noticeable. Please check the photos for confirmation, as they are difficult to see. Thank you for your interest. New retail price: Pot-type water purifier: Approximately 3500 yen Water purification filters (set of 2): Approximately 5000 yen
