Not overall. Some are still shrinkwrapped, but could have been shrinkwrapped by the seller for all I know. Essentially, I mean that they are in a condition that would be acceptable if you saw them on the store shelf. Sometimes it's hard to decide what is mint. For instance, it's well known that the Celtica box came with no cardboard insert and is generally thin so it's not unusual for even the best Celtica boxes to have a crease or ding or 2 in them.

I definitely do not use the term mint to describe a box that has any sign of wear and tear such as worn flaps or tears of any kind.
