QuickFit 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. Angle-D rings hold up to 25 percent more letter-size (8-1/2" x 11) paper than standard round rings of the same size. 1-1/2" capacity holds approximately 350 sheets. The steel rings are mounted on the back cover so pages can lie flat. Binder also offers two clear inside pockets & exposed rivets.
