Every single package my mail main delivers is ripped open. Once, I ordered stamps on line. The mailer was ripped open & the stamps gone. Paperwork still there though. He claimed it got ripped in the sorter. I used to collect coins & buy them off Ebay, but they mysteriously disappeared during delivery. Apparently that includes boxes too, now. He just smiles as he looks me in the eye as he hands me yet another ripped up package/box/mailer, so this is not a "porch pirate" offense.
I want to mail a glitter bomb to myself repeatedly to dissuade him from ripping open my packages. I was thinking a spring loaded false bottom sort of set up. No explosives whatsoever. Just a bunch of glitter, cardboard & spring.
This is occurring in Ohio in the United States of America.
