Bean & Bailey Mug
Bean & Bailey Ceramics designed and make these beautiful two-tone mugs exclusively for us. Each of the four colors available are glossy on top (and inside) and matte on the bottom. They hold 10 ounces of coffee...or other liquid I suppose.
They are food, microwave, and dishwasher safe, however B&B do recommend that you wash them by hand.
These folks are the absolute best. Check out their other stuff too: http://www.beanandbaileyceramics.com/
