A large tumbler that can be used in the microwave

The popular Rivers classic tumbler, Barl Solid. While retaining the popular features such as a generous 390ml capacity, a highly airtight lid structure that won't spill even if it's tipped over, and a hollow double structure, Rivers changed the material to a durable tumbler that won't break even if it's dropped.

Microwave-safe.
The change in material has made it microwave-safe. Even if your coffee or tea has cooled down, you can just remove the lid and put it in the microwave without having to take the trouble to replace the container.

Double-layer structure that prevents condensation
The double-layer structure makes it less likely to condense, so in the summer we recommend adding plenty of ice to enjoy a cold drink. You can also use a straw in the large mouth.
