The easiest and most versatile way to make hot or iced loose leaf tea on-the-go, with zero mess.  All you have to do is put your tea in the double-walled stainless steel cup, let it steep and then stop the brewing by pushing on the plunger. That's all. You can leave, your tea in hand. No sachets or infuser required. Want an iced tea? Just add ice. This might just be the only accessory you need for making tea.
