This is for my afternoon espresso or latte, and I love the look and feel of the cup

Great smaller cup. We use for expressos and double expressos. Works well for these and other smaller servings

I love this cup. It’s my perfect desk buddy. No more trips to the microwave. Battery isn’t phenomenal, but plenty good for the task at hand. I love the look and size. Doesn’t draw much attention to itself. Overall, I’m a fan.
