BrainBashers Puzzles

Puzzle IconYou want to send a valuable object to a friend.

You have a box which is more than large enough to contain the object.

You each have several locks with keys, but not keys to each other's locks.

The box has a locking ring which is large enough to have many locks attached.

You cannot send a key in an unlocked box, since it might be copied.

How do you do it?
