hello [member="sabrina"], the mask wouldn't necessarily have lost seal if it were damaged, besides there isn't actually any information regarding how the masks work, so its hard to make a statement regarding what effect the damage would have, for example what is the role of the tubes that go into the side of the mask from the Kel Dor extrasensory organs? Regretfully I've looked and there isn't much information out there regarding this technology. However, I'm in a great deal of pain seeing as the crushing of the mask drove the metal into my face!! Hopefully I don't look like the joker when all this is over....not that anyone would notice.
