Their "upside down" boxes were prone to dropping the cars. The flat underside surface of what looks
...like a typical box top actually is the surface that the model's tires are resting on. So when I opened my 1960 Sunliner box for the first time, the model dumped out because it was not affixed to the lid. Bent one of the rear fender tips. A real shame because I like that model, although it could use ww's.
