Review: Regular size coffee tumbler - my new favorite! - I love the size of this coffee cup. The design is great as it indents a little so it’s easy to grip. The outside also has a nice feel so it doesn’t slip. Coffee stays hot and the heat doesn’t leak to the outside. I imagine it would keep beverages cold and not allow the outside to sweat. Definitely dishwasher safe. The lid doesn’t leak. Enough said, it’s a great tumbler.
