I purchased this at the "Nabe Museum" of Nakao Aluminum Works in Kappabashi. I stopped using this a while ago when I changed my kitchen to an IH stove, and it has been in storage. Upon listing it, I cleaned it with boiling water and citric acid. There are still some areas that aren't completely clean, and there is a feeling of use, but it is a commercial-grade product and is durable, so I think it can still be used for a long time. The size is 16.5cm in height, 24cm inner diameter, and 6ℓ capacity (there is a 6.0 mark inside the pot. Please check the image). There are some scratches and stains, but it is a used item, so please understand this. Thank you.
