And the back of the card. Bikkuriman stickers don't come in a wrapper, but the cards do.
To make a short story long, any kinds of cards or stickers can be found with choco wafer snacks. Bikkuriman is the most famous and most popular. Lotte issues several other lines of cards and stickers - they are responsible for the set you see above. And there are other candy companies that occasionally issue other products.
And beyond that, it's not always wafers that are in the package. Gum, gummy candies, and even ramen snacks have come with cards or stickers. If I'm able to get a lot of examples together for a single post, I'll give more details.
