This is a "Deluxe Procast Aluminum Deep Pot 21cm" made by Hokuriku Aluminum, likely manufactured in the 1975-1985 period. Diameter: Approximately 21.7cm, Height: Approximately 15.2cm. This item was made by casting a special aluminum alloy containing magnesium, and it is said to be a product with excellent corrosion resistance, saltwater resistance, and alkali resistance. It is an unused, long-term storage item, but due to aging, the characteristic "white rust" of aluminum has occurred in various places (please refer to the images). These can likely be removed to a considerable extent with aluminum rust removers, citric acid, or cleansers, but we would like to hand it over in its current condition to acknowledge its age. Also, the outer box is heavily soiled and deteriorated, so we will only provide the two-handled pot and the instruction manual shown in the images.
