I have used this item multiple times since purchasing it. The lid and gasket show some discoloration and yellowing, but replacement lids and gaskets are sold as a set on online shopping sites, so please consider purchasing a new set if you are concerned. The enamel part has some scratches, especially on the bottom. There is no rust. A commercially available 750g pack of miso paste fits inside. This is a used item, so please take a close look at the photos before considering a purchase. Thank you for looking.
