Much more effective than your average magnetic drink markers, this set is designed with a one-piece construction so you never lose any small parts. This also provides a larger visual cue for drink identification. These attach securely to both wine stems and glass rims, making them the perfect drink markers for standard wine glasses, stemless tumblers and other glassware. Quantity: Set of 6 Material: Food-safe silicone & metal magnet Capacity: Fits most stemware & rims Care: Dishwasher safe
