I'm listing a large group of CDs on Amazon. Many appear to be factory or
distributor sealed.
I assume some are resealed and I'm trying to separate those from the "new"
items."
Apart from bunched plastic clumps, what strategies are there for telling
plastic sealed CDs apart?
Is there a non-destructive test to tell what is plastic and what is
cellophane? An eyedropper of some chemical?
I'd just as soon not undo the wrapping, of course.
