Set of 6 adorable Hello Kitty face-shaped dishes: - Design: Hello Kitty face - Quantity: Set of 6 - Material: Polypropylene - Heat resistance: 140°C (284°F) - Cold resistance: -20°C (-4°F) Thank you for viewing! I went to Sanrio Puroland in 2021 and kept these at home after eating the meal served in them. I've only used them once at home. There are no noticeable stains, but the nose of the Kitty-chan on top is slightly peeled. The capacity is listed as 320ml for the main container and 135ml for the inner container. These are suitable for lunch boxes for kindergarten-aged children. They could also be used as small item containers even if not used as lunch boxes. *Please refrain from purchasing if you are sensitive to items stored at home.
