I bought this thinking it would be convenient, but I never used it because I'm exclusively breastfeeding. It's unused. The first image is the actual product I will send. You can adjust the temperature from 40 to 90 degrees Celsius in 5-degree increments. There is no outer box, but I will pack it carefully! Includes the main unit and instruction manual. It's a lifesaver for busy moms. It makes making milk in the middle of the night easier. I'm new to Mercari. Please understand if my explanation is insufficient.
