Keep wine fresh longer: The vacuum stopper can keep wine fresh for several days by pumping air out of the bottle, preserving the aroma and taste of the opened bottle. The strong seal prevents leakage, even when the bottle is stored horizontally. Long lifespan and high durability: This stopper is made of high-quality silicone and food-grade ABS material, making it strong and durable. It can extend the life of the wine stopper and reduce the hassle of frequent replacements. Note: The stoppers are airtight, but to avoid clogging the small holes used to vent air, we recommend storing the wine upright during use. Easy to use and simple operation: Just insert the wine stopper into the bottle and press down several times to blow out the air. The timer on top allows you to record the opening time and effectively prevents you from forgetting it. Easy to use, easy to disassemble, and easy to clean. Fits most standard wine bottles: Suitable for most red and white wine bottles (not suitable for champagne or sparkling wine). Cork stoppers do not completely seal out the air and are therefore only suitable for preserving wine for a few days. It is recommended to use them within 5 days for red wines and within 3 days for white wines. Multiple uses: Perfect for parties, gatherings, restaurants, clubs, bars, and a perfect gift for wine lovers.
