This is a milk frother purchased in 2022 at a Nespresso boutique. I used it a couple of times and then stored it at home. I have checked that it works for this listing. I haven't used it much and have handled it with care, so I think it's in good condition. "Unprocessed milk" is recommended for making foam milk, and milk with a milk fat content of 3.5% to 4% is particularly easy to make. This type can also make cold milk foam, which is recommended. Just pour milk into the Aeroccino 3 and press the button. You can make milk foam perfect for various coffee recipes that suit the season in a few minutes. You can also make warm milk for cafe lattes, etc. There is an instruction manual, but no box. There are no noticeable scratches or stains, but please consider purchasing this used item with the understanding that it is pre-owned.
