Holds 11 x 14 inch sheets with a flat-laying spine, archival-safe acid-free cover made from 35% recycled polypropylene, and 40-sheet capacity
The Itoya RB1114 is a multi-ring binder designed to hold 11 by 14 inch pages in a rigid polypropylene cover. Its centre-mounted multifold spine lets the book lie completely flat during reviews or client meetings. The matte black steel rings secure up to 40 sheets and the package includes a starter pack of clear protector sheets.
Conventional binders often bow at the spine, forcing pages to curve and making side-by-side comparison awkward. The RB1114 replaces those with a flat-lay design and archival-safe, acid-free materials that prevent yellowing of artwork or photographs over time. The jump is worth it when presentation quality and long-term document preservation matter more than basic storage.
The lightweight polypropylene shell adds minimal weight to a portfolio case while shielding contents from handling marks. Refillable rings allow you to swap or add protector sheets as projects evolve, and the 35 percent recycled content supports sustainability goals without sacrificing rigidity. It fits any workflow that demands flat presentation and archival protection for 11 x 14 formats.

The binder holds sheets measuring 11 inches wide by 14 inches long, matching the 1114 format.
Lift the matte black precision steel rings straight up from the center-mounted multifold spine; forcing them sideways can misalign the mechanism.
The crystal-clear sheets are archival-safe and acid-free; replace them only if they become scratched or clouded, since the binder itself is refillable.
