I have had my morning coffee out of this mug every single day for a year. It is the vessel that delivers CAFFEINE to my face every morning making it one of the most crucial and frequently used items in the house.
To be clear, I drink my coffee in bed. Does this mean that I have two very small faint coffee stains on my comforter? Yes. Yes, it does. But it can not be assumed that I can face the day before half a cup of coffee is consumed. Full stop.
