This is a Combi milk formula pot that keeps water at 70°C. It was very useful because I didn't have to boil water every time I made milk. There is some limescale on the base of the pot (photo 2) and on the pot itself, but the operation has been confirmed. Please understand that this is a used item before purchasing. Instruction manual included. I plan to put the item in its original box, wrap it in packing material, and ship it. Thank you for your understanding.
