This is an aluminum stockpot from Nihonbashi Kiya. The listed dimensions are 240mm, but the actual outer dimensions are 250mm in diameter and 230mm in height. Currently, this item sells for around 23,000 yen. I used this pot when I ran a Japanese restaurant. I haven't used it in the last few years, and I've polished it and stored it in a warehouse wrapped in newspaper. It has a bright, shiny finish that will brighten up your kitchen. The size is perfect for making soup for a large group or for boiling pasta at home. I believe it is still usable, but please check the photos as there may be some deterioration due to long-term storage. I am offering it at a low price including shipping, so please consider purchasing it after understanding and agreeing to these conditions.
