The design of this binder is great for filing and easy access. The"D" 3-ring binder is easy to open and close and the "D" ring holds more that the standard "O" type ring closure. Documents that need to be moved and secured are far more portable filed in binders than stored in drawers.
Although I haven't actually used it yet my binder is for displaying photos of crosses that I made from vintage jewelry to put in a booth I have in Brenham TX to advertise for custom work~
I purchased my first binder over 5 years ago. I sing in a chamber choir and use the black one for performances and rehearsals. The rubber has not cracked or ripped in all these years. I loved this binder so much that I bought a second one in purple for my other sheet music. Nothing else even comes close to the design and quality of this binder.
