Hi Kay,

I've never had a cel arrive bent or had a buyer 
receive a bent cel, so I can't answer regarding 
that situation.

When I send a cel, I use a priority mail box, 
with the cel inside a priority mail envelope 
inside the box.  I tape the envelope containing 
the cel to the inside surface of the box.  If 
it's a cel that is in any way special or 
valuable, I also fill the dead air space in the 
box with packing peanuts.

Done this way, it's darn near impossible for the 
postal ghouls to do anything to hurt the cel 
unless they puncture the box with a long sharp 
object.
