QuickFit View Binder features a unique overlay design that allows a single sheet to create a one-piece custom insert that wraps around the spine to the front cover. Customize your title pages with free online templates. Overlay is made of no print-transfer, PVC-free vinyl. Steel round rings are mounted on the back cover so pages can lie flat & experience less wear. 3" capacity holds 600 sheets. Binder also offers two clear inside pockets & exposed rivets.
