So while everyone has been focusing on the long box (I doubt it's bumper fabric, but anyway) I took a look at the large, abnormally light box (29 in. x 22 in. x 22 in., 9 lbs.) If you assume the box itself is made of standard corrugated cardboard it would weigh ~3.25lb empty, leaving 5.75lb for contents. My bet is the contents are game pieces. One example of what would fit in this box is 3 balls (3 because thats how many we were given last time the game piece was foam balls) each with a diameter of 13.6". If they are made of polyurethane foam (
Think dodgeball balls) with a density of 2.5 lb/ft^3 they would have a weight of 1.92lb each. 3 of these, plus the box is almost exactly equal to 9lbs.
