Protect Your Beverages with these innovative drink covers for glasses. Made with BPA-free, food-grade silicone, these covers keep outdoor and indoor elements out of your drinks, giving you worry-free drinking wherever you are. The tap and seal design prevents the covers from blowing off your glass, locks in aromas, and reduces splashing. They are also dishwasher safe and can be used as wine glass markers, coasters, or small snack plates. Fit glasses and mugs up to 4 inches wide. Perfect for picnics, parties, and more!
