We love the design on this brand NEW tumbler from 2015. It is a rare collaboration between Hello Kitty and Doraemon. It looks like Hello Kitty has just discovered a lot of interesting things in his 4D pocket. This can be used for both cold and hot drinks. It is made of plastic with a soft non-slip foam bottom . The lid pops up and down with a rubber gasket so it seals tightly. Even if you don't use it for drinks you can save it as a nice collectible or decorative piece. It measures 20 cm tall (about 8 inches) and would hold a very large drink.
