Well.. the difference I suppose is that a flat 
priority box is much bigger, so its harder to 
bend through it.  You can't count on the PO to 
take care of a package.. theres no "do not bend" 
area in the PO.. it just gets put in the bin 
with everything else piled on it.  :(  Its sad 
that its such a pretty cel and I was so excited 
I won, and now I'll be a bit disappointed 
everytime I see it -_- gah.

Again, if anyone knows of a way to flatten a 
cel, do let me know.
