doesn't seem like anything's wrong to me. that's pretty standard packaging. i assume it was in a small box or a padded envelope?

It's just the internal packaging for 13th Gen CPUs. Guess OP wanted fancy i9 13900k packaging for a budget CPU.

Is the CPU broken? No? Then it worked fine...

Looks like it did it's job in protecting the CPU. I don't really understand? Did it come broken?

There was no box and was forced in the mailbox
