Got this cel a couple years back when I was in 
college...it was packaged in one of those thin 
tagboard-ish priority envelopes and then in a 
priority Tyvek envelope.  *Nothing* backing it 
to keep everything flat and unbent. >_< There 
was a teeny tiny little "do not bend" stamped on 
it, which the school post office worker didn't 
see, so it was rolled up and shoved in my tiny 
school mailbox.  Miraculously, it survived 
unscathed.
