No teapot has ever created an uproar equal to that made by the introduction of the mono classic in 1983. Tea aficionados and design enthusiasts alike cheered the triumphant synthesis of form and function. The idea of making the sieve almost the same size as the teapot itself was a stroke of genius the tea leaves now would have room to expand and fully release their aroma. The use of non-porous materials further assures the purity of the brew: the sieve is made of stainless steel mesh, and the pot is heat resistant Duran glass.
