Did you ever find anything?
I
think that one might be able to 'fake' something like this with waxed paper/parchment and a microwave.
Kraft caramels, about four or five, centered on wax paper or parchment, topped with additional parchment, and melted until just softened, then rolled flat and chilled.
I'm assuming this is for some kind of school project?
I'd tell them HOW to do it, and provide a roll of parchment paper and a bag of Kraft caramels.
