This cute Rilakkuma tumbler can be used for both cold and hot drinks. It is NEW and made of plastic. The lid has a snap latch with a rubber gasket underneath to secure the beverage. This was a 2015 Lawson convenience store collaboration so the design is no longer produced. Even if you don't use it for drinks you can save it as a nice collectible or decorative piece. It measures 14 cm tall (about 5.5 inches) and holds a large drink.
