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" capacity holds approximately 225 sheets. The steel rings are mounted on the back cover so pages can lie flat. Binder also offers two clear inside pockets and exposed rivets.
