Like @teamrocketop said, someone a while ago posted a picture of their psa cards in post card pocket pages. I also cannot remember who it was as it was like a year ago I saw the post and asked them about it. So whoever you are if you see this, please take the credit. But here is some of my PSA cards in the 4 pocket post card pages:
For them to stay in the pockets of the pages you have to have the card in a PSA slab sleeve. You put the card in the sleeve, push that into the pocket, and then fold the adhesive flap over the top of the pocket and adhere it to the face of the pocket. You could do it on the back of the two top pocket but the two bottom you cant obviously, but you can hardly see the overlap or the adhesive strip.
Heres the brand and the title. I believe I bought them on either Amazon or ebay pretty inexpensively.
Once again all credit goes to the other person I got the idea from, I wish I could remember… thank you for such a good way to binder these!
