Five styrofoam boxes inside of cardboard boxes and a sixth styofoam box without a covering box.  The boxes look old because the foam+cardboard are 20 to 25 years old and were used for multiple moves between states, but they are still in pretty good shape.  These were typically used for transporting materials on dry ice.  You can take one or all, and inspect before you take if you are of a mind to. --Courtland
