What are these unusual items & their box?
Magnet Key Holders. It is likely that the top part with the character on it has a magnet behind it. They keys go on the loop below that's put through the paper packaging. In this box (and likely all others) you get 2 key holders.
This box has Sonic & the little animal penguin. But, the outside of the box has Eggman, the walrus & Tails too, so it's likely they were also made. The cube shaped box has a window over 2 sides so you know what you'll get. These are uncommon, and the box even more so, making it extra interesting to see.
