I use ultrapro binder pages. Nearly all of my cards are in binders and I don't sleeve them prior. I have only had issues once and it was junk era left in a hot attic. Otherwise, thousands of cards from the 1880's to 1969 are bindered with no ill effect. T205/6 Cobbs, Ruth, Gehrig, Williams, Sullivan and so on with no fear by me. They are also in a fire safe. I do monitor for humidity, but that's it. I also have thousands from the thirties to sixtiess in boxes with no protection. This hermetically sealed stuff is overkill. A sleeve within a slab within a sleeve within a binder page or box is wild stuff. A friend collects ephemera far older than our oldest cards and many are rare historical documents. They are not even stored as heavily as a Tom Brady foil deluxe green rubism card of today.
