【Vintage】National Electric Warmer NK-90 Showa Retro I am selling this as I no longer need it. This is for keeping food warm on the table. It cannot be used for cooking. Please be aware of this. Operation has been confirmed. As it is an old product, there is no switch; it turns on when the power cord is plugged into an outlet. The size is 14.5 x 14.5 cm for the metal part, and 21 x 21 cm for the main body. Please note that these measurements are approximate. There are some scratches and stains on the heating element. As this is an old product, please check the condition in the photos. Showa Retro A simple and stylish tabletop IH cooker, NK-90. - Model Name: NK-90 - Voltage: 100V Thank you for viewing.
