Clean Touch binder promotes cleaner schools, offices, homes and hospitals with built-in antimicrobial 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. Locking round rings are mounted on the binder's back cover to reduce wear and let letter-size pages lie flat. 4" capacity holds approximately 700 sheets. Non-view binder also offers a label holder on the spine to identify contents, two clear inside pockets, vinyl-covered chipboard, and heavy-duty construction for frequent use. Binder is 100 percent recyclable.
