"This mug is super cute, but as others have mentioned, it is very small. It only holds about one sip of coffee. You better just keep the whole pot beside you so you can keep refilling it if you truly want to use it as a coffee mug. It would be cute as a pencil/pen holder on a desk, which is how I will most likely use it, but $15 for a pen holder is a bit pricey. If it were a "normal" coffee cup size then I think $15 would be fine, but it's only about 3" tall."
