It's a single large flat box (not boxes), somewhat crushed at this point. It doesn't really keep the cats off the Roadster, but it does do a fine job protecting the car. I think it's crushed because one of the cats likes to drop down from the rafters onto the car & the box is now the landing zone. I got wise to that when the soft top supports were bowed in the opposite direction one morning. The box seems to eliminate that problem, too.
Really, you need the cats with the box so that you can be appropriately impressed with what a great job that box does. Without the cats, it's just a box.
