The lining has noticeable stains. There were also small stains on the outside. Please check the photos. It was stored for a long time at my parents' house. Please understand. I do not have specialized knowledge, so I cannot provide details. I apologize. (´；ω；`) As this is a personal inspection and home storage, if you are even slightly concerned, I apologize, but please refrain from purchasing. (><) We ask for purchases from those who understand.
