Going Stemless® Magnetic Cocktail Charms are upscale, glass-dazzling charms for use on ALL drinkware, especially stemless wine, martini, champagne, and margarita glasses. They're also ideal on plastic tumblers and acrylics for lake weekends, tailgating, and impromptu get-togethers! It's a fabulous solution for drink identification on stemmed or stemless drinkware! Place near the rim above liquid on all drinkware to maintain their elegant sparkle and shine. To remove, simply pull from the front and back magnets, but not from the decorative charm itself. Rinse the back magnet with warm water and they're ready for the next celebration! Cheers!
