View binder features antimicrobial material that inhibits the growth of bacteria, mold and fungus. Slant-D rings have a higher page capacity compared to same-size round rings. Back-mounted metal rings let your letter-size pages lie flat. Customize the overlays on the front, spine and back with free templates available online. Nonstick polypropylene material prevents toner transfer. Four interior pockets offer plenty of storage. Each pocket holds up to 20 sheets. Binder also offers concealed rivets for a professional appearance and a sturdy chipboard core.
