A cocktail connoisseur knows that the only way to adequately serve drinks is with our 16 oz pure hammered copper tumbler. Enjoy using them to enhance the flavor of mixed drinks with vodka, rum, tequila, gin, whiskey, beer, wine. Also works great for keeping your drinks colder, longer with beverages like iced-tea, coffee, lemonade. Our mugs are great for everyone! A beautiful handcrafted addition to any home bar. Food-safe lacquer resists tarnishing; not microwave or dishwasher safe.
