The most convenient teapot you will find anywhere! When the tea is 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 leaves with one of the best infusers on the market. Easy to clean and dishwasher safe. Made with Tritan, a plastic specially-formulated to be safe in hot-temperature applications and is 100% BPA-free.
