Back in april I got 14 surprise prize boxes and one of them had the normal thing in it as well as a Hidden Surprise prize box. I do not have proof since I opened it back in may sadly. I don't know if there is anything I can do to get proof as well.
The "Hidden surprise prize box" Came with two additional prize boxes.
We need images, and more information in general. For example: What two extra boxes came out?
