Our 15-oz. Double Walled Latte Mugs have a layer of air between the walls that keeps hot drinks hot, and cold drinks cold. They’re great for entertaining, because they’re so versatile. You can use them for coffee, tea, espresso, lattes — even cold drinks and ice cream. These oversized mugs are mouth-blown and made of highest-quality, crystal-clear borosilicate glass. Dishwasher, microwave and freezer safe. Includes 2 mugs.
