IngenuiTEA teapot is the most convenient device for brewing loose leaf tea - we guarantee it. Add leaves, pour hot water and let them steep. When ready, simply place it atop your cup. This will cause a valve at the bottom to release: crystal-clear tea flows down, while the mesh filter retains all the tea leaves. The tea brewer is also super easy to clean - just rinse it out with water or pop it into the dishwasher. You will wonder how you got along without one. IngenuiTEA is made of BPA-free plastic and fits all cups up to 9.5cm in diameter.
