Elevate your daily beverage ritual with the Bodum BISTRO Jumbo Mug Set. This set of two premium 450 ml mugs is expertly mouth-blown from durable, heat-resistant borosilicate glass. The defining double-wall construction acts as a thermal insulator, expertly keeping your hot coffee or tea warmer for longer while ensuring the exterior remains cool and safe to hold. Conversely, it keeps iced coffees and chilled desserts refreshingly cold without any unwanted condensation on the outside.Designed with a streamlined silhouette that embodies the "form follows functionality" principle, these elegant mugs are surprisingly lightweight yet robust. They are engineered for complete convenience, being dishwasher, microwave, freezer, and oven safe up to 180°C (350°F). A crucial hydrophobic silicone vent at the base regulates internal pressure for safety. For lasting enjoyment, handwashing is recommended to protect the pristine glass from potential chips. Exercise care as with all glassware; inspect for damage before use and always handle hot items with attention. Experience the perfect fusion of sophisticated design and practical performance.
