you're absolutely right on the distribution method of the boxes. that seems to be what most people have trouble understanding. XD

They aren't random boxes, they're an item. you get every pose included in the item, but of course you need more than one to wear all the poses! one of the poses is an actual box, and it's named after the Pandora's box of Greek myth.

they also don't have the exact same items, one is more angelic themed and one is more demonic themed, but they work as a set. each one has a half-mask, a staff, wings, a box, and a cute little angel/devil girl, among other things.
