Place the Kool Twister in the freezer for 1½ hours or overnight.
Open your bottle and pour a small amount into a glass to make room for the Kool Twister.
Insert the Kool Twister into the bottle neck & ensure the rubber seal is tightly secured.
When you’re ready to pour the perfect glass, simply pour straight from the bottle without any drips or spills.
To use the stopper option; pull the Kool Twister slightly out from the bottle. Slide the rubber stopper down over the hole, then reinsert into the bottle.
