It is a genuine piece of art, the BODUM Ice Tea Jug BISTRO! It can be used in three different ways: as a tea jug with the filter inside, as a storage tool with the santoprene knob sealing the stored liquid from outside influences and, removing the lid (santoprene, stainless steel), as a simple glass jug carrying any drink you like. The whole body of the jug including the handle is made of heat-resistant, ultra-light, see-through borosilicate glass interacting with the filter through multi-faceted colors and - believe it or not - giving the thrilling impression of looking into the eye of an insect.
