Her packing sucked, I also would doubt that the post office did not tell her that it was not a good idea to ship any item like that especially over seas.
It clearly says she did not care.
But to be fair, you got your money back (I assume in full), she should get her "blaster" back. Maybe she could re-sell it as "battle damaged ROTJ Skiff stunt blaster"
Glad to hear that it worked out for you.
