A Mercenary Steel Box is given to you when you gain the favor of a wandering Mercenary - Monk or Viking. If you convince one to join your team, but you don't have any space left in party he will give you a box instead. Getting it from Vikings is generally cheaper - two gifts of 20000 and they're yours.
