Thank you for viewing. This is a set of two Disney-designed color-changing tumblers, a collaboration with Kirin beverages (limited to the Aeon Group). I have kept them at home, but I am selling them because I have no opportunity to use them. The designs are Pluto and Donald Duck. Since they are unused, I have not been able to confirm the color change. Raw material resin: Polypropylene Heat resistance: 80℃ Capacity: 520ml As a bonus, I will include a Mickey Mouse pouch. Shipping will be via regular mail. I am also selling other Disney goods from the Kirin collaboration. I may be able to offer a discount if you purchase multiple items, so please feel free to comment. If you have any other questions, please ask in the comments section. Thank you.
