How does this superwow accessory work? Like a teapot. Except the clear, BPA-free Tritan™ lets you watch as your tea steeps. And when you're ready to sip, just place the steeper right on your cup. You'll feel a rush as the weight magically opens a valve, and your infused tea flows out through a specially-designed filtration system. Then, when you lift the steeper, the valve closes automatically. It just might be the neatest, coolest way to steep.
