Each bar is wrapped in cellophane, which are then wrapped in the normal outer packaging. To make the 4 pack, they simply took 2x two packs and put them on a cardboard tray,and then wrapped those.
I don't think I've ever gone through so much unwrapping for candy.
They're my absolute weakness. I usually get two two packs and was like "oh they make a four pack now?" Thinking it would be less packaging.. nope, it was more!
I wonder how quickly they would react if enough people mobbed them on social media to redesign the packaging. π€ Because surely, using more material for packing is expensive and they could actually save money by being more sensible with how they're packaged.
