The inner pot is a stainless steel milk warmer with a user-friendly design that includes a temperature adjustment function. After opening, I only cleaned the inside once with citric acid as instructed in the manual, and it has never been used, so it is in very clean condition. The original outer box and instruction manual are also included. - Brand: raicop - Model Name: Milk Warmer - Material: Stainless Steel - Accessories: Instruction manual, original box - Power Cord: Yes Thank you for looking.
