Reference price: 20,466 yen (tax included), selling for 12,000 yen (tax and shipping included). No discounts. As for the advantages of enamel lids: For those who want to use the lids cleanly for a long time, just like the main body, "enamel lids" are recommended. Also, compared to plastic seal lids, you don't have to worry about odors or color transfer, and they are easy to clean, so you can use them cleanly for a long time. And, if you use them with the main body, you can maximize the features unique to enamel. (When heating food by directly applying heat to the main body, if you cover it like a pot lid, the heat will pass through better, so it can also be used for steaming.)
