Purchased in 2019. It was washed after each use and soaked in bleach regularly. Before listing, it was wiped down with alcohol, and the nozzle and hose were bleached again. Yellowing and cloudiness are visible on the nozzle, hose, and cup lid. Adapter, box, and instruction manual are also included. Operation confirmed. ※ Due to Mercari regulations, this is a medical device, so the main unit cannot be sold. Only the accessories will be sold. (This is stated due to regulations) For those who understand that this is a used item. Thank you very much. (^^)
