>>21449225iinm, they're still available industrially (as-in you have to work in the industry to get them) but they're much larger than "normal" Oreo cookies.
I know a barstaurant that uses those iron pupu platter things as tableside firepits for s'mores in the winter months and it comes with the gihugic marshmallows, enormous graham crackers and gargantuan Oreos for you to make them yourself. I'm surprised they haven't been sued into oblivion yet after some dumb fuck burns himself or some shit.
