The Matchbox case is well used; plastic is wrinkled and punctured, needs a good cleaning, has one blue plastic tray inside with a broken corner, and the other blue tray is missing. So it holds 36 cars instead of 48.
The cars have been played with, but not abused, generally in good used condition.
I've noted the exceptions below.
