Double Wall Sweet Heart Shaped Glass Coffee Mug 8.5 Ounces, Set of 2

Enjoy a heartfelt cup of coffee in this Double Wall Sweetheart Coffee Mug! Made with a double layer of mouth-blown borosilicate glass, each glass will keep hot and cold drinks insulated while the outside surface will remain comfortable in your hands. Two layers of borosilicate glass are used to give it ample insulation, style, and to create an optical illusion. The double wall glass creates an effect where the drink appears as though it is 'floating' within the glass. When filled with your favorite beverage, the unique heart shape of this heart coffee or tea mug will be 'lovely' to the eye. Please Note: We recommend using care when placing ice or metal utensils into the glass to avoid fracturing the inner layer. Avoid soaking in water for long periods as it may cause the glue to disintegrate. (the glue is a unique trace of the manual blowing process.)
