Unlike any other whiskey glass currently on the market, our 10 oz glass features a scale replica design of the Grand Canyon running along the inside of the glass. 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 canyon. 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 summer selections with Liiton whiskey accessories. Any whiskey lover will be thrilled to have Liiton at their next 4th of July BBQ, Labor Day get together with family or pool party with friends!
