Most of us use binders, primarily for storing punched documents, paper, and catalogs. They're great for that. But we can also add to their versatility by adding accessories. By adding sheet protectors or pockets, you can store loose, unpunched sheets, photos, and pamphlets, without harming or damaging them by punching them with holes. Zippered pouches and envelopes also neatly keep writing implements close at hand.
