I'm so grateful for a lid for this cup! The steak slides a little bit, but still a whole lot better than no lid. The sliding lid comes with color options for the slider. Very well made, and works great.
Great way to extend the battery life of my Ember mug! My mug easily keeps coffee hot for twice as long (or more) than without the lid. The lid is a VERY tight fit on my 10 oz mug. It’s really a bit too tight for my comfort.
