Looks innocent until the coffee hits. This 11 oz heat-reactive mug is black at room temperature, then reveals a bold F*ck This Sh*t as soon as you pour something hot. It's microwave-safe and lead- and BPA-free. A hilarious gag gift for coworkers, White Elephant exchanges and anyone who's done with today.
