Thank you for looking! This is a hot pot and yudofu (boiled tofu) set. The pot has a double-layer structure, with a copper exterior and a stainless steel (?) interior. The inner pot can be heated directly on the stove. Then, by placing the heated inner pot into the copper frame, you can enjoy warm oden at your dining table ♪ It has been stored on a shelf for a long time, and while the outer box is not in new condition, the contents are brand new and unused. It's perfect for this season, and I hesitated to list it when I found it on the shelf, but my children prefer curry over oden, so I decided to sell it as I won't have a chance to use it this year (￣^￣). The copper exterior is beautiful, and in today's world where plastic products are common, I think this is a rare item. How about enjoying a luxurious restaurant experience at home?
