Mug Revolution started off with a simple concept: To make a beautiful, comfortable, and durable handmade mug. We think that we've accomlished that, (as do our customers!) and have added a few new variations on our mugs over time. We call these mugs our Mainstay Coffee Mugs - these are mugs that we make up ahead of time and try to keep in stock so that we can ship them out as orders are placed.
