Widely used wine and champagne bottle stopper 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; just rinse with cold water after use. Made from high-quality stainless steel (SUS304) and food-grade silicone seal for safety and durability. Features smooth edges and a fingerprint-resistant finish. Effectively preserves freshness by sealing the bottle mouth with a silicone center shaft that blocks air exchange, helping maintain flavor and carbonation. Provides a 100% leak-proof seal to keep wine tasting fresh for up to 10 days.
