Reading all the coments about styrofoam one thing comes to my mind. You can not put some lighthouses back in the styrofoam because trees and other items were assembled after removing from the styrofoam. Removing these items for repacking can damage them because they have barbed bases.

I got rid of the styrofoam from these boxes to insure the lighthouses would not be damaged if someone, not knowing the problem, tried to repack them.

Just my thoughts.
