The reinforced rubber causes it not to rip the spine and the flaps easily. It is costly but it is woth buyingit over the plastic ones. Another downside is that it takes a little force to open the rings.
for the price i did not expect to replace this binder every month and a half....we need a 3" binder that holds 5 folders and papers that does not fall apart! very disappointed!
I have purchased an identical folder in the past from Staples and when I needed another I was happy to see that they still carried this particular folder.
Okay so this is one of the BEST binders out there. Even if it is a generic store-brand product. Given its price it has served me well. After using it for half a year dropping it numerous times and scraping it against many walls it's still there. The rings are still even the spine no worse for wear...etc. This is an amazing product. (There are only two problems: begin complaints 1. The flimsy little pockets behind the cover and on the back...they don't do anything useful. If the binder was designed with something similar to what's on the cover that would be great. 2. It's not remotely waterproof. If there are binder sleeves out there already sorry but that would be very useful here. end complaints) Overall this is lovely.
