Width 8.9cm, Height 9.2cm, Depth 8.9cm Material: Heat-resistant glass, Silicone Bodum Pavina Double Wall Glass 0.25L 2pcs No original box Excellent heat and cold retention to keep the deliciousness Made by skilled craftsmen using a blown glass method, each Bodum double-wall glass has a double-walled heat-resistant glass structure. It excels at heat and cold retention, keeping warm drinks warm and cold drinks cold, thus preserving the deliciousness of your beverages. Also, it is less prone to condensation when filled with cold drinks, and you won't find it too hot to hold when filled with hot drinks. The unique design, which makes the drink appear to float in the air, is also a feature. It can be used in a variety of ways, as a drinking glass or as a dish for your meals. Microwave and oven safe Bodum double-wall glasses made of heat-resistant glass can be used in the microwave and oven. This is because the water-resistant silicone vent (patent pending) on the bottom of the glass allows only air to pass through, maintaining a constant air pressure between the outer air pressure and the air pressure inside the double glass. The silicone vent also prevents water from entering, so please do not peel it off.
