Totally concerned with D-rings damaging cards but I haven’t seen it happen yet with any of my sets. I know the old O-Ring binders could pinch cards.
I did make spine labels for mine which you are welcome to use if you have any interest: www.elitefourum.com/t/new-binder-spine-labels-for-pokemon-base-crimson-invasion/15664/1
Also working on 1" versions of them as well as an alternative or in conjunction depending.
Hmmm… perhaps using binder sleeves and storing each set on it’s side would alleviate any risk of D-Ring damage… Going to have to look into that.
