Thank you for viewing. This is the pressure regulator weight and the steam nozzle cover for the Asahi Kasei pressure cooker "Katsuryoku Nabe (SW type)". There is one heat-related scratch. (Photo 5) These are common parts for the SW type. They cannot be used with the currently mainstream ZK type, as the shape and size are different. This is a used item, so please check the photos carefully and purchase if you understand the above contents.
