These Champagne Stopper Cages from Youngs can be inserted by hand and do not need an expensive champagne corking tool (as natural champagne corks do). Champagne cages and corks are designed to use with champagne bottles for corking any sparkling wine. Seal the bottles with the plastic corks and place a wire cage over the cork and twist the base of the cage to the underside of the lid of the bottle to hold the cork in place. These multifunctional plastic corks can also be used with underbungs to collect sediment, or even as they are and washed and reused.
