Hi Christian, I can't speak to the ball dome cases but I think this is an interesting question in general. I imagine you might have seen the recent interview with the Cooperstown archivist who said that anything plastic and nonbreathable is bad for baseballs. Makes sense. I don't use the ball domes, but like many I use the Ultra Pro UV cubes and keep the room blacked out as much as possible 95% of the time.
I understand that archival acid free boxes offer more protection from off-gassing and oils... but at the same time, I don't feel like that's any way for me to enjoy my collection. I have had minimal toning/bleeding/fading (knock on wood) thus far, but I've only been collecting autographed baseballs for the last 8ish years.
I'd be curious what more seasoned collectors have to say in regard to their experiences with keeping balls in cubes over longer spans of time?
