This binder has a flexible cover (I wanted a firm cover). This binder has a pouch with flap closer inside the front cover (I just wanted a pocket). This binder is a D ring (which I normally would like but it makes the binder wider and therefore now won't fit in my usual storage space.
These binders are perfect to organize smaller projects. The D ring makes all the difference in the world. I use different colored binders for different projects. These seem to wear pretty well also.
