How to use Zac – The Dripless Wine Pourer

Cut along the dotted line and leave the ring on the neck of the bottle.

Roll the circular part making sure that the small hole remains toward the outside.

Insert the cylinder you have obtained onto the neck of the bottle.

Pour the wine!

Remove ZAC from the bottle and rinse it under running water, also hot.

Use the small hole to hang ZAC in a place where it's easy to find the next time you need to use it.
