Widely used The wine and champagne bottle stopper is suitable for opened wine in all standard bottle sizes, including Champagne, Cava, Prosecco, and Sparkling wines, as well as red and white wine bottles. Easy to use and clean Simply insert the wine and champagne stopper into the bottle and secure the handle around the bottleneck. When you hear a click, it is securely sealed. The stopper is reusable and can be cleaned by rinsing with cold water. Material safety Designed for health and durability, it is made of high-quality stainless steel (SUS304) and food-grade silicone seal. Features smooth edges and a fingerprint-resistant finish. Perfect freshness preservation The silicone center shaft tightly seals the bottle opening, preventing air exchange inside and outside the bottle. This helps maintain the flavor and carbonation of opened wine, ensuring 100% leak-proof performance and keeping wine fresh for up to 10 days.
