This cute and colorful rainbow design 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 is a San-X original produce and we believe that 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. The bottom has a metal and no-slip felt finish. It measures 15 cm tall (about6 inches) and holds a large drink.
