Squeeze the bottom and use the built-in foilcutter! It comes packaged with one cartridge which will open between 60-80 bottles of wine. The Legacy features a custom designed insertion guide and needle guard, as well as a patented cork release feature which removes the extracted cork from the opener with a simple twisting motion. The Legacy utilizes the same low-pressure cartridge to gently remove the cork from the bottle without affecting the taste of the wine or harming the environment. The Legacy is the next generation in wine openers from the company that put the fun into opening a bottle of wine.
