I searched the shelves at my local Staples for a binder that would take pages longer than 10.5". I needed a binder that could hold 220 pages 11.5" long by 8.25" wide from a bound textbook that came unglued. The Better Binder attracted me with its D-style rings sturdy build fold-over flexibility and mechanically attached locking lever. The metal lever at the bottom end of the 3-ring mechanism limits the binder to pages 10.5" long. I bent the mechanically attached lever back and down with a pliers until it popped out of the 3-ring mechanism. The mechanism now opens and closes by manually pulling the two-halves of the center ring open or pushing them together to close. I carefully separated the pages from the book binding fabric and used a standard 3-hole punch (a few pages at a time) so they fit the binder's 3-ring positions. The textbook's soft front and back covers and all pages easily fit on the 3-ring mechanism and I can flip through the pages more easily now than when the textbook was bound. The 11.5" long pages do not protrude beyond the binder covers.
I am quite impressed with the quality of this binder. I have bought cheaper binders in the past but have found that they tend to deteriorate and quickly become useless.
Since there are no real paper alternatives I bought this heavy duty plastic one. I bought four different colors to organize for varied groups (church golf NFL pool union activities). I wish it had two inside sleeves one one each cover but I think it will do the job.
