Bistro mugs from Bodum (sold in sets of 2) are handmade by expert artisan of insulated, double wall glasss. Not only does the air between the glass layers keep hot drinks hot and cold drinks cold, beverages seem to float in mid-air, creating a striking appearance.

Bodum's insulated glassware is made from durable Borosilicate glass. Borosilicate glass is a strong, heat-resistant glass that weighs less than traditional glassware. Used to make scientific lab glass, borosilicate glass (medical grade glass) is stronger than traditional "soda-lime" glass and can be used for everything from drinkware to cookware. Borosilicate glass is dishwasher safe and will not become cloudy over time; you can rest assured that after 100 cycles, the glass will be as clear as the day you bought it. Because this glass is mouth-blown, each one may have slight differences in height, thickness & weight. Please use care when placing ice into the glass to avoid fracturing the inner layer. Please also avoid using metal spoons or placing the glass into a crowded dishwasher. These glasses will help to keep hot drinks warmer and cool drinks cooler. For best results retaining heat, pre-heat the glass before use. Dishwasher & microwave safe
