A rocks glass, also known as an "Old Fashioned" or "lowball" glass, was traditionally used for drinks with a minimum of ingredients that would be served over ice. Today, any drink served over ice benefits from the clean, classic look of a rocks glass. Colorful swirls make these pop -- each is handblown and spun to create the unique patterns, so no two are identical. The team behind Impulse! believes there’s nothing better than getting together with friends and family, mixing a concoction of choice, and sitting back to enjoy. These glasses, trays, and accessories will enhance your good times, whether your beverage of choice is a dry martini or sparkling water.
