DivineDevDON'T OPEN THE BOX WHEN IT ARRIVES this is a keter class object, also don't move we're sending someone to help you
**SCP Agent: ** What’s in the box?
SCP Scientist: Nothing
SCP Agent: So, what’s the big deal? Just open it.

It’s a hole in the universe that is inexplicably cordoned off from the air in this room, and everything else in it, by a flimsy cardboard shell.
SCP Agent: …
SCP Agent: Is that bad?
SCP Scientist: Very.
“Soundwave… what is in the box?”
“Hatsune Miku. Hatsune Miku is in the box.”
“What is a Hatsune Miku?”
Soundwave's Arch Nemesis
If it can be sent by mail it is probably not a Keter class object. Object class does not imply danger level
