1. Place the paper cutter at 90 degrees on the top of the wine bottle, turn the blade with the bottle mouth stuck, and cut the foil paper;

2. Insert the bottle opener needle into the wine bottle from the middle of the cork, and protect the bottle mouth with a plastic protective sleeve;

3. Inject air into the bottle by moving up and down until the cork slides out from the bottle mouth (usually 4-7 times per bottle can be opened);

4. Use the small plastic slider on the protective sleeve to withdraw the cork from the air needle.
