Altalume Color-Changing Mug (11oz)

This heat-reactive ceramic mug brings a quiet little ritual to your mornings. This mug has a glossy finish and black exterior when cool; add a hot drink and the Altalume design appears. A perfectly refined, slightly mysterious look that fits on a cluttered desk or a tidy kitchen shelf. It’s light enough for daily use, safe for microwave reheats, and made from lead- and BPA-free ceramic.

ALTALUME means high light — our pursuit of clarity in a cup.
