I like that the binders are cut 3/4 .
Two binders are slightly damaged/ badly made.
And I can't close the box now after sleeving all cards. If I take one binder out it closes. This works now so thqt I can read the binders to get familiar with the classes and cards.
If the card stock would have been thicker that would have been an even greater issue.
I had no problem putting two cards in a slot in the binder.
I am a bit worried though that the binders will need replacing if you use them a lot.
At this time they make some great reading material.
What I'm probably going to do is toss the insert. Everything will fit in the box if I do that. The box is so huge already, no idea why they didn't just increase the height a bit more so everything fits with sleeved cards.
