In fact, I recently shipped a razor to one of our members here, and it had arrived with the box opened and the razor taken out of the wrapping. It had then be put in again without wrapping. Luckily it arrived whole, but something else could have happened to it, causing it to get lost, without anyone having acted in bad faith.

That might have happened to yours. And it being a fixed handle razor, it could have simply cut itself a way out. There is also no point in complaining about that scenario, because mailing knives and razors goes against the rules of the post. that is also why I didn't complain about my packaged having been opened and the razor being put back in the package loose.
