Nicely made, with good details. The side mounted rings (on the interior of the back cover, as opposed to the spine of the binder) make it really nice for keeping the pages secure and unmussed. Plastic sleeves in the covers and exterior spine allow you to personalize/label/brand the binder with slide-in paper printed for that purpose. Pockets on both inside covers lay flat and admit a few sheets of paper each. The 1/2" ring really doesn't work well for a binder of random use - there's just not enough room for the kind of volume you normally look for in a binder; and while the manufacturer's claim that it holds 125 sheets is probably true, in strictest terms, it's not practical for something you want to be able to flip through over and over without damaging the hold attachments. This would be excellent as a space-saving binder that has a dedicated purpose - like for keeping a product manual or some other reference item that isn't going to require a lot of in and out, or flipping through pages on a regular basis. Or, it would work well with sheet protectors as a file for masters.
