I have a few signed balls in my collection that are fading. They're not in direct sunlight, never have been, but it's just happened over the years.

Is there ANYTHING I can buy that will protect against further degradation? Any recommendations on cases that will protect the signatures from further fading? I've had them in basic plastic ball cubes.

Specifics on what I'm dealing with are HOF signed balls, obtained at card shows when I was a kid, on low grade non-MLB balls, in ballpoint ink.
