We purchased and began using a beautiful matched set of coffee mugs. Unfortunately, while nursing coffee around the kitchen and dining area on a leisurely weekend morning, we frequently lost track of which mug was whose. This is the same phenomenon that has led to the invention of wine glass charms. The form of the mugs/glasses (perfectly matched) interferes with their function (serve a beverage to multiple people).

It was, therefore, a pleasant surprise to find a set of Hausenware mugs. They are painted identically on the outside, but the inner surface of each is a different color—form and function perfectly blended.
