if you send it by mail.
make sure you have a roll of film (kodak) in the box. that way you can tell the company that is shipping the box, that the package must not go through an x-ray machine. if it goes through an x-ray machine the film will be erased.
the company will mark the box accordingly and then noone x-ray it to see what's inside.
next.
don't put your return address on it. EVER.
and for the address you're sending it to. Make sure you put someone else's name like some fake name. but keep the real address. it will still get to your friend's house, but just incase the authorities track the package to see who gets it, your friend can prove to them that the package was sent in error because his name will not be on it.
Understand??
that's about it
