About this project Sealing Keeps Wine Fresh: The Mini Wine Sealer provides an airtight seal that locks the gas in the bottle to preserve the open wine bottle. Wine corks are suitable for all common red and white wine bottles with an inner diameter of 18-19 mm. More convenient to use: The wine bottle opener adopts a rotating design. The upper cover is loosened counterclockwise and tightened clockwise, which is convenient and quick. Lightweight and smart design: The silicone wine stopper fits the arc design of the sparkling wine bottle. It is not only lightweight, weighing about 1.01 ounces, but also has 4 steel balls inside that can clamp the neck of the bottle. After installation, there will be no water leakage even if it is tilted or laid flat. EASY TO STORAGE: This wine cork measures 1.53" (3.9cm) * 1.59" (4cm), it is small and easy to store. The round wine stopper housing is made of wear-resistant ABS material for easy cleaning. The inner seal of the wine bottle stopper is made of food contact grade silicone material, which is more secure. As a PERFECT GIFT: 3-pack wine sealer fits standard wine, beer and soda bottles (note: only for wine bottles with an inner diameter of 18-19mm). Perfect for events, festivals and parties, it makes a great gift.
