Best cork remover!
Color: 7-in-1 Silver, Size: Rechargeable
I love this wine bottle opener. With just a zip, the cork is out! No struggling, no breaking of the cork. Perfect. I’ve bought several for gifts.

Don't pass this one by
Color: Gunmetal Grey, Size: Rechargeable
This is the best wine opener we ever had...push button once...it goes in, pulls cork out, then reverses and drops cork in your hand...all with one push of the button. Long battery life between charges.
