I bought this at Shanghai Disneyland last year! I didn't have much of a chance to use it before returning home, so I'm offering it for sale to a CookieAnn fan. It comes in a case with a strap, so I think even small children can use it♪ Please consider purchasing if you're interested. It holds 220ml and can keep things warm for 6 hours! Instant purchase and price negotiations are welcome! ⭐︎
