Now you can say goodbye to bitter tea once and for all. A simple twist activates the built-in smart filter, stopping the tea from steeping once the desired strength is reached. The tea leaves only need to be removed after you've finished drinking. A fusion of tradition and innovation gives the Stelton Emma tea thermos its harmonious body made of high-gloss stainless steel. The beechwood handle adds a modern touch and draws from the natural materials of the past. Stelton's Emma teapot features a blue or gray hue that beautifully complements the bluish and grayish tone-on-tone colors of the series.
