There are things that you never knew you needed until you have them, and then can’t imagine living without. The donut warming mug is one of those things, and it is perhaps one of the greatest inventions of our time. You may think that’s a preposterous claim, and that it doesn’t compare to innovations like smartphones or a particle accelerator capable of producing miniature black holes, but just try to make that argument with a mouthful of warm donut. This is a gift that’s sure to be coveted in your white elephant exchange, if you can actually part with it after it’s in your hands. Better get two.
