>>58762915>>58761790>Previously I mostly used KMC Perfect fits but they leave so much space around the cards in the slots I find they move around sometimes and I'm trying to avoid thatI think that might be more of a binder thing, I have some spare cards in my dragonshield binder in just a KMC sleeve or even naked and they don't move around in the least (and this is the binder that got slightly loosened).
My autism with multiple sleeving is mostly from other collections I have and due to having worked in the past in an archive for glass negatives and other historical stuff and whenever it would be possible, multiple opposite/layered sleeving/packaging (be it with inert non off-gassing polymers or breathable acid free cellulose linings) was always preferred due to the inherent safety, as a pollutant/moisture would physically need to the slalom around those protections instead of taking a shortcut. Archival techniques and materials are a rabbit hole you never want to go down if you want to enjoy your collections.
