Keep your wine fresh longer – Minimize wine oxidation by sucking the air out of the bottle. Simply pump the wine vacuum stopper several times until it is firmly seated. This helps preserve the taste of your wine bottle for weeks instead of just days. The perfect solution for your home, bar, or restaurant. No spills or leaks – The vacuum rubber seal fits most wine bottles as well as others with similar characteristics. It preserves better than the original cork and extends the wine's freshness. Safe & High Quality – Perfect for households, hotels, clubs, bars, and more. Made of high-quality and durable food-grade silicone inside and food-grade ABS outside. A safe, non-toxic, and premium wine accessory for the human body. Record the opening date – Record the date of the bottle on the stopper's scale. Please note that it is only a recording and does not count down automatically. Easy to check the best taste for the wine.
