Not your average steeper. With the Menna infuser basket, you can choose to start/stop your tea's brewing at any point. Find the flavor that suits you and with an easy twist of the ring, you can tailor your tea, just the way you like it. Our double-walled vessel keeps things hot or cold for up to 6 hours. The easy lock top allows you to spill the tea with your friends, not in your bag. Did we mention it’s dishwasher safe and BPA free?
