This binder has a durable cover (yet not ridgid) opens and closes with ease. D rings keep pages from getting jammed between the cover and rings. I use this binder for my very important Church papers.
This is the highest quality binder I've ever seen. I own 4 of these binders from 1" to 1.5". They are extremely well made. The rings line up perfectly but they also have a protrusion on one side and a dent on the other side that centers boths sides of each ring to its mating side. The "hinges" are clearly deliniated but rugged enough that they will last for decades. The spine offers a simple method for labeling as does both the front and the read face. You honestly cannot do better with any loose leaf notebook.
I liked the selection of colors and thought that the sturdy construction would hold up to the frequent use it would get in our preschool setting. Each teacher liked getting her own bright color for her class list and emergency info she has to keep with her at all times.
I use the product to keep classroom records organized. The smaller one is great! I also have a 3 inch one that is awful! The rings do not stay closed when it is full of papers.
