This is quite a simple product. It’s just a strong shot of cool/menthol flavour for you to add to any if the current range to turn it into cool and fresh fruit flavour. The shots are pretty strong so just add a few drops from the bottle and shake. If you want more cool just add more. Remember you can always add more but you can’t take it away. Find your perfect cool strength by adding a little at a time. DO NOT USE ON ITS OWN.
