Turns out, it's just junk food for peasants: you can't taste the chocolate, the wafers look and feel like very dry, tasteless black bread, they crumble terribly, but the whole thing still sticks together because of the filling, which is quite awkward. In the end, the filling is the only thing that has any taste or texture. I checked the expiration date – it was produced a month ago, and it has a shelf life of a year, so it's fresh.
Now I'm wondering if they've replaced the ingredients with cheaper ones, which I don't really believe, because even in a franchise, it should be made according to the standards of the brand, or if my memory is playing tricks on me, which is also strange, because I still see people who talk about it unironically as some kind of standard candy of its kind.
I should have just bought some day-old cookies, honestly.
