If your office doesn't pay for a cleaning service, and every employee is left to wash their own dishes, you'll want to maximize every cup, plate, and spoon you bring to work. So when it comes to caffeine you might want to swap your current mug for this $14 double-duty alternative that holds 5.5 ounces of coffee, or 1.5 ounces of espresso when flipped upside-down.
It's dishwasher safe, too, if your company is at least willing to spring for one of those in the break room. And besides coffee, it seems just as useful for making a cup of soup at lunch, followed by a smaller portion of pudding for dessert. Or a small glass of libations after work, followed by a shot of whatever keeps you going. [Cool Material]
