Bodum Double Walled Glasses With Handles 10326 10 Drawing on modern technology and innovative design Bodum39s Canteen collection puts a new twist on everyday drinkware. The walls of each vessel are hand blown with two layers of clear glass creating an optical illusion that the liquid is suspended inside. Cut in slightly tapered clean lines they have an almost futuristic appeal that emphasizes the relationship of form and function. Crafted of borosilicate glass which is also used to make scientific lab equipment the pair is exceptionally strong lightweight and thermal. The two layer construction also resists heat and prevents condensation so no matter what temperature the beverage is the glasses remain comfortable to hold and safe for any tabletop. 13.5 oz Pair Dishwasher safe Crafted of lightweight thermal lab quality borosilicate glass Two mouth blown layers make liquid inside seem to float Winner of the prestigious European IF Design Award
