Review on 🍶 Ceramic Coaster with Splash-Proof Silicone Insulation by David Robinson

Bought two of these mugs. Arrived in great shape. Coffee cools a little quicker than stainless steel, but I can usually drink before it cools. So a 10 ounce mug, like a larger one, cools down before drinking. I love that you can reheat it in the microwave if needed. 4 stars because the top gasket and bottom ring of the microwave stand have to be removed. It's okay, it's just that Star would be better off if she didn't need it.
