Has anyone here managed contact with family/friends in iran recently?

So I have started collecting recently, and I even got a binder! Turns out my binder is ringed and I only found out that they are not very good afterwards, I will take extra care. However I have been hearing about acid free pages? I am less knowlegeabable about that, I plan to keep my cards in the binder for a long time, I am unsure if the one I got is acid free or not (https://pt.aliexpress.com/item/1005006661194168.html?spm=a2g0o.order_list.order_list_main.5.577bcaa4Gb8VoB&gatewayAdapt=glo2bra for refference this is the one I got) what is about and should I bee too worried? Not all my cards are sleeved
