2 Wine Stoppers for the Price of 1

Air is what dulls an opened bottle. The Mini Wine Stopper twists into the neck and closes it airtight, so the second half is still worth pouring days later.Push it into the neck, twist the top clockwise and four steel balls grip the inside of the glass while a three-layer silicone seal closes the bottle airtight. It is leak-proof, so the bottle can lie flat in the fridge door. Twist the other way to open. Not for sparkling wine.
