Set of 169+ (1-169+)
This set was released in Chocolate Surprise eggs, 2-3 caps per egg.
They are two cardboard jigsaw piece halves, which slot together, and then stickers for the front and back.
The highest number I have seen is 169, though the set likely goes higher.
We recently had an issue with a malicious attack and have lost some image data. I am working to restore what I can :/!
