Cardinal SuperLife Binders have a heavy duty, solid plastic cover and crack-resistant hinge for tough-as-nails durability that's super easy to use. We've worked hard to make these hard poly covers worksite proof, student-proof and long-lasting. This large workhorse of a binder survives the school year, job site, backpack and car with equal ease. SuperLife 5" inch binders have Slant-D rings that hold more paper than your standard round ring binder—up to 1,050 sheets each. Rings are back-mounted for a clean, uncluttered spine. Easy Open ONE-TOUCH rings open, close and lock with one simple motion. Whether you're creating one big binder for school or a dozen binders for the home office or work, ergonomic SuperLife binders make loading and reorganizing pages easy. Look for this no-pinch upgrade over standard binders on your office or school supplies shopping list. Covers are made of non-stick material that resists ink and toner transfer for clean, smudge-free covers and are archival safe for documents and photos. An adhesive spine label helps you spot the right binder at a glance. A handy shelf pull helps you haul this large notebook to and fro. Durable construction makes this the perfect emergency notebook or household documents binder for your home office bookshelf. Add binder dividers for total 3 ring binder organization. 5" Binder. 1,050-Sheet capacity. Black.
