JUNKO IGARASHI Sweet Mama Tabletop Pot Warmer 23cm Electric Warming Tray Unused item. The tray part warms up just by plugging in the power cord, and you can keep pots and other items warm. Operation confirmed. I confirmed that the warming tray gets warm enough that you can't touch it with your finger. The cord has yellowed slightly due to long-term storage. Otherwise, there appear to be no noticeable scratches. Food warming plate Food warmer plate Electric warming tray Food warming plate Tabletop heater Heating device Warmer Food warmer
