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.

### ⭐⭐⭐⭐⭐ Keeps Coffee HOT
*by K***N on June 4, 2026*

Amazing thermos! Very sturdy, cute, and functional. It really holds up, I can put coffee in it at 6am and it's still hot by 1pm, warm by 4pm. The lid is easy to pop open but has a tight seal. I prefer to hand wash mine but it's very easy to clean. Lots of color options.
