When I got my box of Nazca cels, the pan cels 
were actually wrapped around the other cels, so 
that they formed a big circle in the box. 
Amazingly,...this actually didn't hurt them! O_o 
I was shocked, but when I laid them flat, they 
flattened right out as if nothing had ever 
happened to them. I guess that shows that 
cels /are/ pretty resiliant to some aweful 
things.
