This mug has a rather unusual top, but once you realize its purpose, you’ll know that it’s the best mug ever. This lid-like on top of the mug serves as a warming plate for a donut, cookie or any other pastry. It uses the heat from your coffee or tea to warm up your pastry for a more delicious treat! There are two openings on top, a large one that allows for easy pouring and stirring, and a small one for drinking (mainly for left-handed people). The mug is made from porcelain and it’s microwave and dishwasher safe.
