When you wake up in the morning, you will need fuel to go about your day. That fuel is, what else, but coffee. To perk up and stop feeling groggy, get the Wake-Up cup, fill it with your favorite coffee and you will feel fresh and happy thereafter. While the Stacked Ceramic Mug is more for fooling others, the Wake-Up cup is to cheer yourself up first thing in the morning.
From a pair of droopy eyes initially, they will transform into a pair of big round eyes when the cup is filled with steaming beverage. Basically, the heat sensitive ink will respond to the change in temperature from the hot coffee and the eyes will brighten up to make your day.
