Material: Champagne bottle stopper made of durable plastic or stainless steel that won't rust, crack, or fade, safe and non-toxic wine bottle accessories. Design: The champagne bottle stopper's double buckle design securely fastens the bottle stopper to the bottle, and the high-quality silicone parts fit snugly against the bottle neck, preventing odor loss. Easy to use: When sealing, simply push the wine bottle stopper into the top of your wine or champagne bottle. When opening again, simply open the top button. After use, simply rinse with water and let dry. Easy to clean and store. Instructions: Place the champagne stopper on the bottle and press down both wings. This completely seals the bottle and prevents carbon dioxide from escaping.
