A cup for tea (or coffee, or hot chocolate, or any other drink that you have to stir), that you don't need a spoon for. A ceramic ball placed in the bottom of the glass allows you to just swirl the vessel to stir your beverage!
And the best design part? That weird looking base provides a place for the ceramic ball to go when drinking, so you don't get splashed (or have a ridiculously hot ceramic ball hit you in the face).
I love innovative products like this!
