Man, this trading box thing is really annoying me! I can't afford a case of these things. And, if they can't guarantee a complete set in the case, you have to look around for someone who has the one(s) you need or buy another case. Even a complete set will cost you cuz sellers mark them up because they opened the boxes just to find a complete set.
The last boxes had two sets of 5 in them. If you managed to get an unopened box, you got a set of normal and a set of clear haired figures. You could always buy a box and sell the other set. That's what I did.
