Tim JamesHey Matt,
That was going to be my next point, if nobody brought it up. I'm a professional picture framer, and in our industry, there are differing grades of glass that reflect UV rays. I'm curious of what happens inside a slab after it is sealed. If there is an issue within a slabbed card, it would take years to see with the naked eye. Unless it is sealed in an air tight way, who knows. Even if that is the case, certain plastics can gas over time if the environment in which they are kept doesn't have radical temperature changes.
