Developed by Bodum when the British Tea Council commissioned them to develop a new way of brewing tea. Boil water to temperature (varies depending on the type of tea), place your tealeaves in the stainless steel filter, pour the hot water in the teapot, Wait 3-4 min (varies depending on taste and type of tea), and press down the plunger. You now have perfectly steeped tea. No need to remove the filter, no mess, no burned fingers, only the true unforgettable and delicious taste of your preferred tea. The teapot is made in brosilicate glass with a steel infuser and lid. The clear glass makes the infusion visible at all times, making it a very attractive table piece. Everything can go in the dishwasher, the jug (without the rod and lid) can go in the microwave.
