I’m having trouble finding out the best dimensions of inserts/sleeves for kep1er’s trading cards and stickers. I know they are slightly bigger than your standard pc but I’m struggling to find any info on how others are storing them. I have an a4 binder. If anyone knows what dimensions/brands would be best for these please let me know!

Pictured are examples of some I have on the way for reference from Fly up and Fly by eras!
