Cardinal EasyOpen 1" 3-Ring Non-View Binders, D-Ring, (12112V3)

Durability
Heavy-duty materials that stand up to continued use and resist sticking and wrinkling make the Cardinal Easy Open 1-inch slant ring binder convenient for travel and use anywhere. Its steel rings are sturdy and back-mounted, so the pages it holds lay flat and hold up after repeated opening and closing.

Ease of Use
The Cardinal black locking D-ring binder has an Easy Open feature that locks shut with one simple motion, so it's easy to use and there's less chance of it catching your fingers. The slanted rings lock smoothly, and can also be opened and closed with just one hand.

Large Capacity
Cardinal's locking D-rings offer more capacity than standard round rings, so you can store larger amounts of paper, while two interior pockets create a space to hold and organize loose materials, like handouts, business cards and brochures.
