This is a SNOOPY tumbler. It's made of plastic, so it doesn't have any heat-retaining function. The inner card has a Snoopy design. Capacity: 420ml Heat resistance: 100℃ Cold resistance: -20℃ Size: Height 17cm x Diameter 8.5cm Thank you for looking. How about it for Snoopy fans? I've kept it stored in a cupboard without using it. It will be shipped as a standard size, so I can't lower the price any further. Thank you for your understanding.
