Hello Kitty Tumbler The lid is made of silicone, and the body is made of polypropylene. The heat resistance is 220°C for the lid and 120°C for the body! The outer box was crushed, so I disposed of it and stored it in a bag ( >_< ) It's new and unused, but it's been stored at home. It's a great deal for those who don't mind! #HelloKitty #Tumbler #Kitchen #Tableware #DailyNecessities
