Oxidation of Cigars??

And, your point?

Don't they have glass doors?

Well, that's what I was assuming @Merovius was getting at. Indeed it's got a glass door, but it's heavily smoked and a UV filtering element. The cigars are either inside boxes or in deep shelves, so they're not exposed to light. The light inside is disabled and it sits in the darkest room in the house, which is VERY dark. Most of the shelves also have cedar spills covering them. They're not for light, but rather environmental baffles, but they also likely help prevent any light penetration.
