Depending on how you handle the pcs - if they are just stored in a binder, they should be ok. If you maybe carry the pcs around with you then swap out the sleeves if they get dirty or something. I had a pc in a sleeve and carried it around in one of those keychain holders and i changed the sleeve as i put the pc into my binder bc the old one got kinda worn after like 2 months.
Actually I don’t take them out of the binder except to take pictures. As for the photocards I carry with me I usually take the unofficial ones
And Thank you 🌸🌸
