It might be a little easier to wake up with a smile on your face when there is one staring back at you. Not a morning person? No worries: there are frowning, winking and other varieties as well. It is a bit cute and arguably somewhat kitch but the simple colors and elemental design approach offset what could be an overly kiddish approach to design. Alternatively, just buy the entire rather well-matched set and pick one to suit your mood with each morning coffee.
