This multi-functional cooking appliance does six things: grilling, simmering, steaming, boiling, and keeping food warm. After using it a few times for takoyaki, it was stored for a long time. The heating plate of the main unit is dirty, and there are scratches on the inner surface of the plates (see images). The outer box is tattered, and damaged or deteriorated parts have been repaired. Power-on confirmation has been done. - Brand: National - Model: NK-850 - Functions: Grill, Simmer, Steam, Boil, Keep Warm - Features: Multi-functional cooking appliance with 6 functions in 1 Thank you for viewing.
