Crafted from the finest quality mouth-blown borosilicate glass, the Moderna double-wall whiskey glass is the summation of the Ozeri Artisan Series of award-winning handcrafted drinkware. Both heat and condensation-resistant, the Ozeri whiskey glasses feature double-wall insulation that preserves a spirit's ideal temperature, structure, and notes within the sanctuary of a suspended inner chamber. Shaped with a modern, twisted flair, the Ozeri whiskey glasses are crafted from durable, stain-resistant borosilicate glass. The double-wall construction prevents exterior heat from reaching the inner walls, and condensation from forming on the outer walls. In addition to fine whiskeys, the Ozeri glasses serve as an excellent vessel for Tequila, Vodka, Rum, Cognac, Soju, hot or chilled Sake, and more. Ships in an elegant and carefully packed color-printed gift box and backed by Ozeri’s No-Hassle warranty. Each glass measures 3.6 x 3.6 x 4.3 inches and holds up to 10 oz (300 ml).
