Are you looking for an alternative to the spine and the rings?
Rings always prevent the user’s hands from reaching a page, and the sticking-out spine empty or full, always takes the same scarce storage space. The hard, brick-like covers only add to the pain. It is hard to replace, but quite uncomfortable in handling.
Because of that, there are a number of people avoiding it and users looking for a binder without rings, without the metal ring mechanism. The available solutions like “Clamp Binders” or “prong
folder” is usually limited to a max of 200-pages.
To avoid the limitations and preserve the good side of the venerable Ring binder, we developed a “No ring binder” 
or Ring-less binder.
The metal mechanism is eliminated, and binder dimensions are reduced to practically the dimension of the paper sheet.
Plus:
1) Our solution is made from a flexible sheet of material
2) Instead of rings, we have flexible Ties
3) Instead of choosing between 6 different sizes commonly offered in traditional Binders, you have two basic arrangements:
a) V-binder from 1-350 sheets (equivalent to a 2″thick ring folder)
b) Z-binder from 1-800 sheets (equivalent to a 4″thick ring folder). Just two sizes instead of six.
4) There is NO SPINE. Full or empty our solution’s external dimensions are always as thick as the number of pages they contain.
