This a set of component organizer trays for the Puerto Rico 10th Anniversary Edition. This stores all of the components in the box, including all the expansion buildings and nobles. The player boards and instructions manual fit snugly on top of the two trays, with a small amount of breathing room for extra printouts. This insert is specifically designed for the Puerto Rico 10th Anniversary Edition box, and retains the cardboard liner. I don't know if it fits the regular edition box, but it can probably be re-scaled slightly if there is a difference in size.
