Wilson Jones® Heavy Duty D-Ring Binder with Extra Durable Hinge, 1", Black - 1" Binder Capacity - Letter - 8 1/2" x 11" Sheet Size - 250 Sheet Capacity - D-Ring Fastener(s) - 2 Internal Pocket(s) - Polypropylene - Black - 1 / Each

Binder features two interior pockets and a Locking No-Gap D-Ring mechanism that locks rings closed and keeps them aligned so sheets will not tear, fall out or hang up on rings. Metal rings are back-mounted to reduce wear and let pages lie flat. Cover and pocket material resists toner transfer so ink from printed papers won't stick or mark binders. Pocket Guard on both inside covers holds loose papers secure in pockets. Binder also includes a label holder on the spine for easy identification, sturdy chipboard core and exposed rivets. Durable construction protects important documents and is made to last.
