These are the best of the best, I think. I mainly use these and buy mine from this guy. He shipped me 4 of them for only $4 shipping. They are bulkier than normal ones. They are extra rigid, meaning more stiff and durrable. I don't think they make holders anymore that are not good for your notes. Most currency specific holders are acid free and all that jazz.
