Naturally add a salty note to your favorite tequila. Enhance your tequila shots with these reusable shot glasses. The high quality, food-grade Himalayan salt is hand-carved into a solid glass for long-lasting use. After each shot, flip glass over, or pat dry, to keep a salty brine from forming. To clean, quickly rinse under cold water and pat dry with a paper towel. Store in a cool, dry place when not in use. Do not put in the dishwasher. 4 Glasses per order. Each shot glass is approximately 3 inches tall and will hold approximately 1.5 ounces of your favorite tequila.
