I've got quite a few (30?) TF's still MISB/MOSC. That said, my son (okay, I admit it, me too) is itching to play with a couple. Say I take the plunge and open them up. Then assume that the condition of the toy drops to C-7. Is retaining the packaging still worth it at this point? Or maybe a cutout of it? Or just flattened (throwing away internal packaging and/or bubble)? Thoughts?
