I bought this about 3 years ago in a shopping street in Osaka for around 30,000 yen. I've used it about 3 or 4 times, and after that, I've kept it stored at home. There is a slight stain on the outside, but the inside is in very clean condition. Please refrain from purchasing if you are concerned about minor details, as this item has been stored at home. Thank you for your understanding and purchase.
