I particularly like these notebooks/binders for filing tax records as they have easy open rings plus 2 pockets in the front and back cover. With the clear pocket on the exterior I am able to label them very easily and after 7 years I can RE-label and reuse for another year.
I wanted something between too small and too heavy to carry. This was perfect. Nice work on opening and closing the Rings without pinching. And a nice selection of bright colors to make them easy to find!
