Our three ring binders make indispensable home, office, and school supplies. While there are many binders available, only our durable binders offer the economical paper storage and organizational value you've been searching for. This important document binder features a clear overlay along the front, back, and spine, allowing you to fully customize your binder. A non-stick polypropylene and chipboard cover adds durability and effectively prevents the transfer of ink or lifting of copy when materials are inserted into the cover or placed inside our black binder. Three binder rings with double boosters hold 8.5 x 11 sheets of paper or sheet protectors with ease. The rings are mounted on the back lid, allowing pages to lay flat while also preventing wear and tear on documents. Two clear interior pockets provide additional storage with enough space for notes, photos, business cards, or full-size pages. 1" D-Ring holds up to 225 sheets, basic assortment 4 pack: black, blue, red, green.
