This binder cost a little more but it's worth it. It's sturdy with rubber edges that make it stay in place. The D-ring makes your pages lay flat and easy to work with.
We use these binders for handbooks which are distributed to kids. Previous cheaper binders had an avreage life expectancy of about 6months. I have yet to see one of these be destroyed. The price is worth it but I would prefer to see some bulk rated pricing.
