Get a good look at this behemoth because I don't think it is physically possible to create a binder any larger. A similar 6-inch Binder is available in white as well if that fits your color scheme a little better, but it is still the same high quality D Ring Binder you need. Thanks to the use of the D-Ring you can store a whole lot more paper than the standard round ring. The documentation says it'll hold 1300 sheets of paper and I'll take them at thier word, I don't have 1300 sheets to test it with.
Inside this Huge Binder
This does of course make me wonder what it takes to fill this beast and what it is like once it is full. Assume that it is filled with 1300 pages of the fairly common 24 lb paper which should weight around 16 pounds total (don't worry the math is complicated). 16 pounds isn't to heavy, but it probably isn't something I'd trust my grandmother to carry around. But as you lug your extra large heavy duty binder around the office you can rest assured that once upon a time that same weight in ham was worth 1.6 million dollars.
