Using these champagne flutes is a piece of cake. Just attach the base to the glass, pour in your champagne or other beverage, and you're ready to toast. When you're done, since they're disposable, you can simply throw them away. But if you want to be eco - friendly, you can recycle them. Remember, these glasses are not safe for the microwave or dishwasher. To keep them in good shape while in storage, make sure the base and glass are properly nested in the package to prevent any damage. Enjoy your celebrations with these stylish and practical glasses!
