I used this less than expected because I was mostly breastfeeding. I only used it in the microwave. It was much easier to use compared to Combi. I don't think there are any damages or major stains. Includes instruction manual. It will be shipped in this cardboard box. If you would like additional cardboard packaging, please comment. Shipping costs will change, and it will be an additional 300 yen. No claims and no returns, please.
