Query: Excellent Item, If Pricey

I'm not sure what the other reviewer received, because mine are well-sized for comics from the 1960s to modern. I actually place two in each sleeve, with an acid-free backboard in-between. I have several hundred comics from one series (The Legion of Super-Heroes is many versions), and I am extremely pleased with the difference between my old boxes and the notebooks I'm transitioning into.Pros*Heavyweight, MUCH thicker than standard paper sleeves*clear, but doesn't pick up too much in the way of fingerprints*well sized, not tight, which I appreciate for my 1960s Adventures - I don't want to shove them in* Easily fits two comics and a backboard in each sleeve*Archival safe*Fit in regular binders (with free space, but it's not a problem)Cons*These puppies aren't cheap, but completely worth it to me!
