The Peak Porcelain Tea Mug is heavy and thick walled, so your tea will remain at the correct temperature even longer. The infuser is easy to load and clean and fits just right in the mug itself. This mug comes with an extra-handy lid to optimize brewing, also doubling as a coaster for your strainer after steeping. The super-fine tea infuser could also be used with other tea cups, or your favorite teapot.
