I had to put Japan in brackets for this one, because I plan on reviewing the UK version of Kit Kat Orange soon, and there may very well be a difference between the two.
Mine wasn’t in a box so I can’t comment on that, but the packs were full orange, with a little picture of an orange on. Opening the packs reveals a decent smelling orange smell.
The taste isn’t quite up to scratch though, I’m sure the British version will be better than this. This doesn’t taste quite balanced, the orange is a little too strong, then fades almost completely, it doesn’t seem to be mixed too well. It’s a little hard to describe, but this wasn’t bad, just a little odd and unbalanced, maybe the orange flavouring they used was different, maybe it was the chocolate, though it was probably both.
