Purchased new around 2023. Used a total of about 5 times, and after each use, it was washed with running water, disinfected, and stored. As of December 2025, this is the same as the "Merci Pot Perfect Set S-504" sold on Rakuten Ichiba for 10,890 yen. Instruction manual included. Although there is some tearing, the quick guide is also included and can be used immediately. *Please note that according to Mercari regulations, the main unit is a medical device, so the main unit cannot be sold. Only the accessories will be sold. (This is required to be stated according to Mercari rules.) Thank you for your understanding.
