Clean Touch binder promotes cleaner schools, offices, homes and hospitals with built-in protection. Agion's all-natural additive fights against the growth of bacteria, mold, fungus and mildew for the life of the binder. Agion's additive is nature's antimicrobial and is based on silver (not nanosilver). Agion has global registrations including EPA and FDA. Clear overlay on front, back and spine of this view binder allows easy customization. Nonstick material will not lift copy. 3" metal round rings are mounted on the back lid to reduce wear on your letter-size paper. Two clear inside pockets offer extra storage for loose documents. Binder also features exposed rivets and is made with polypropylene over a sturdy chipboard core.
