The thing with boxed toys though, is that it someone may have managed to get the tape off and then reseal it, but the carded toys that are glued down are definitely a factory error. I agree though that there is very little added value in packaging mixups/errors. The only value is in production errors (wrong colour plastic/paint, paint or plastic contamination, wrong paint apps), or a very early production/packaging change (BW rock bubble, Cheetor eye colour, etc).
