When opened, leave it in the fridge?

Kinda stupid question here. If I only eat half a Plenny Bar a day (with my breakfast): once opened and half-eaten, should I leave it in the fridge for the next day? Or not necessary? Thanks.

This may be a personal taste thing, but I keep mine out of the fridge, they get a bit too hard for me in there. Just fold the wrapper back around it and it is fine to use the next day still.


Yeah, I used to do that too. But I’m too exaggerated when it comes to safety so I thought I’d like an official response.


Any answer yet ?
