I bought this a few years ago for around 15,000 yen. The main pot part is broken, but the two pots, lid, and power cord are still usable, so I'm selling them. This is the 4-piece set shown in the first photo. It seems you can use the pots directly over a flame even without the main pot. This is a used item and shows signs of wear, so please refrain from purchasing if you are concerned about minor details. I have the original box, so I will ship it in the box shown in the second photo. Please note that there are no instructions.
