Coravin 6 Pack Pivot Stoppers - Keeps Wine for Years - Pivot Wine Storage System - Specially Sealed Plastic for Glass Wine Savers - 100% Argon Gas

It’s easy to use and works!

This whole system is great. So nice to drink the rest of the bottle a few days or a week later.

These are great to have around so you can sample multiple different styles of wine.

Coravin advertises this as preserving wine up to a month. So far it meets this promise plus a little extra. New corks feel a little too tight for the wine bottles I’ve tried so far, so I can’t comment on longevity of corks. Hopefully the cost of gas doesn’t end up being too expensive, but so far it seem to be pretty efficient with gas.

Works perfectly with the Coravin Pivot. Wine stays in great condition for at least a month. Very happy with having a few extra stoppers so we can sample from multiple bottles.
