MISB Definition?

For toys such as the Soul of Chogokin series, that do not have figures tied down with ties (at least from what I can see), with a window panel that can flip out and the toys just taken out, what would be the definition of MISB? Would it just be the clear sticky tape being intact? Because I know some downright geniuses who can actually remove the sticky tape, then replace it without anyone knowing.
Were there ever any transformers after G1 that came in a similar fashion, without ties, just a tray you could slide out?
