On the outside, this white porcelain tea mug looks puristic. But once it is in use, it shows its true purpose. Its double-walled design allows it to always stays nice and cool on the exterior while long-lastingly retaining the temperature of the tea poured inside. Its special Reactive Glazing gives the mug its distinctive finish. We recommend matching it with our P & T Porcelain Teapot and the P & T Small Plate for placing the used infuser after brewing your favorite tea.
