I purchased this new in May 2022, but I only used it once or twice because I was exclusively breastfeeding. I have stored it at home in its box. I have cleaned and confirmed that it works before listing it. I will pack it in its box, then in a paper bag, and ship it via Rakuraku Mercari delivery. - Brand: LARUTAN - Included items: Instruction manual - Internal structure: Stainless steel bottom Thank you for looking.
