It does its job pretty well. Holds paper; displays something on the front holds sheets inside the cover etc. Rings appear sturdy and I'd be surprised if anyone ever accidentally opened the rings on this thing but it's not too hard to open them either. Seems rigid enough too; was a little concerned about fragility but not anymore.
The binder does it’s job. What is more impressive is the cashier at the Princeton NJ location. Every time I go there I ask him about an item and he specifically knows the location every time! He has glasses and hair that is combed forward. He’s always so helpful! 5 big stars!
