This is the mighty Jojo’s Banana Bag. (AKA Jojo’s Pouch)
The exact content of the banana bag when released is unknown. It came with a Jojo’s key-chain attached to the zip mechanism.
Israeli version
Alternative version
An Israeli version of this banana has been released as shown in the picture below. The difference in coloring might imply that the Banana Bag exists in different colors, however those two are the only we know about.
Israeli banana picture is from an anonymous private collection.
The Israeli version came with a King Krema figure even though the promotion was exclusive to France.
An alternative version also exists without the black fabric surrounding the plastic pieces.
A promotional video of the Jojo’s pouch can be seen below:
