We had those in Bulgaria for a number of years before the fall of communism. They were restricted to use only by foreigners buying with foreign currency and locals could only gawk, but never buy. As a child I remember seeing Kinder Surprise eggs and Ritter Sport chocolates, and watching ads for Hot Wheels toys and paint-by number sets I could never play with. It scars you for life.

Years later I saw paint by number sets at a store as an adult and then bought two and spend a weekend doing just that, because I had been dreaming of doing it for years. Ritter Sport is everywhere in the US now, but when I see it, I'm just reminded of the misery of a childhood behind the iron curtain. It's gonna be a loooong transition for the victims of the Kim regime.
