Product Name: wine stopper

when relaxing, I want to have a good taste of wine, but I worry that I can't finish it once. With the increase of time, the wine will contact the air and gradually oxidize. At this time, you need a vacuum storage method with zero air to keep fresh for a longer time. It needs to be matched with the attached bottle stopper, and then use pumping vacuum vessel to repeatedly pump up and down until the click sound is made, which means that the pumping is completed.
