Feeling the Monday blues, or need a mid-day pick me up, or maybe just wanting a relaxing cup of tea? Whatever the case, enjoy your hot cup of coffee, or your favorite hot latte in a Mantra mug this season. When room temperature, or cold, these mugs are solid black with a design of your choosing. But, it gets better than that, when filled with a hot beverage of your choice, your mantra magically appears and the full design is displayed. Who knew a cup of coffee could look so good?
