My daughter was trying to get the ingredients for the frosty boots. I ran the race twice and got a green and blue box. I was able to give the green to her, but the blue was bound. I opened the blue and of course it had what she needed but everything from the package was bound to my character. Fortunately the green box has the same contents and she was able to get her boots. So the question is what is the difference between the green and blue boxes other than the blue being bound to your character?
Blue Box has possibly more items and included gear is usually of at least one grade better(at least blue) quality. Green boxes though also have a lesser chance for blue gear, so it might appear the same. (that's what I think I observed anyway).
