Features double helix self-pulling and auto-ejection technology. The Activ-Ball® range of corkscrews brings a new level of simplicity to opening your wine. The patented corkscrew removes the cork from the bottle, then the red ball – the Activ-Ball® - pushes it right back off the screw. No more twisting or pulling! Designed for use on flange-top bottles as well as standard bottle necks.
