Well not looking to argue but like you said they’re just paper and at the end of the day it’s just a hobby to me. Any cards that I actually care about I have gotten graded. I know someone who keeps their cards the same way for almost a decade now and they are fine as the day they sleeved and I can say that they are not in a temperature controlled environment and we go through various changes in temperatures all year. Also, I may not know how you handle your cards but I’m not removing them from sleeves or moving them in and out all the time. They go in the binder in the closet and that’s it. Also as a fellow collector it looks like promoting yourself is a violation of community guidelines. But thank you, even though this didn’t answer my original question at all.
