davidstea tea steeper for loose tea with lid, bottom dispensing tea infuser (16 oz / 473 ml) davids tea how does this superwow accessory work? like a teapot. except the clear, bpa-free plastic 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.
