This paper model is Olette's Munny Pouch, based on the Kingdom Hearts II video game, the papercraft is created by Mickey103. Roxas and his friends in the Simulated Twilight Town spend the second day earning munny for a trip to the beach by doing odd jobs. However, once they go to buy the tickets, Riku bumps into Roxas and snatches the Munny Pouch, since the beach had not been programmed into the simulation.
This Munny Pouch filled with Roxas's hard-earned munny is later given to Sora, although the pouch is treated as a Key Item, and therefore the munny within the Munny Pouch cannot be spent, or otherwise used for any purpose. [Source: khwiki]
