Marketing Information: Deluxe QuickFit Heavy-duty Spreadsheet View Binder features a unique overlay design that allows a single sheet to create a one-piece custom insert that wraps around from spine to front cover for quick identification and easy insertion. Wraparound overlay resists ink transfer. Free customizable inserts are available online. Clear interior pockets on front and back covers secure loose documents. Heavy-duty, back-mounted rings hold 17" x 11" sheets and allow pages to lie flat. Binder is made with a high percentage of recycled content.
