I couldn’t find a plastic box, so I used an old white van, by then I forgot what we were trying to give away, so I just assumed it was free candy. Now the police want to talk to me. 0/10 do not recommend using a plastic box with “books” written on the side.
Doesn’t need to be any design flaws, a few minutes with a welder and/or a truck load of concrete at the door once they’re in there would render the whole billionaire problem “solved”, Hotel California style.
