From the folks over at Thinkgeek:

No need to build a tea dispenser into your existing astromech droid (there could be tea and oil mix-ups if his wires get fried), because there’s this R2-D2 ceramic teapot to the rescue! No superfluous special features to speak of: it holds tea and pours tea. Or you can use it to hold and pour other liquids, if you’re not a tea person. We won’t judge. Either way, it’s an adorable addition to your kitchen, and a flat-out necessity for a Jedi tea party.
