Clean Touch™ binders are protected with an all natural, silver-based antimicrobial additive. Built-in protection fights the growth of bacteria, mold, fungus and mildew on the binders surface. Antimicrobial protection does not wear off and lasts for the life of the binder. Agions additive is based on silver (not nanosilver)—Natures Antimicrobial. Clear overlay on front, back and spine for easy customization. Two clear, inside pockets provide extra storage for loose documents. PVC-free, acid-free and archival-safe.
