Unlike any other whiskey glass currently on the market, our crystal glass features a scale replica design of Yosemite's Half Dome running along the inside of the glass with the elevation of the mountain etched on the outside. Enjoy pristine whiskey without ice or stones. Just store the freezable whiskey glasses in the freezer, pour and enjoy. Our glasses chill and aerate bourbon, scotch, cocktails, tequila, and vodka as you swirl the drink around the face of the mountain. This Patented, 18-second Chill Charge Technology is approved by distillers and connoisseurs alike. The glass is made of premium, high-quality crystal that is thick enough for any cocktail. The heavy glass is unbreakable making it ideal for your next BBQ party in the garden. No more worrying about your friends breaking your thin, fine crystal whiskey glasses. Discover the ultimate winter selections with Liiton whiskey accessories. Any whiskey lover will be thrilled to have Liiton as a gift for Galentine's Day.
