The OEM Avery Durable Reference Binder AVE27553 features a durable construction that is ideal for frequent reference. Wider front and back binder panels fully cover standard dividers and sheet protectors, keeping your paperwork and tabs protected. Slant-D rings provide a higher page capacity compared to same-size round rings, allowing your letter-size pages to lie flat. This binder accommodates approximately 500 sheets with its 2 ring capacity and includes two interior pockets, each holding up to 20 sheets. Designed with exposed rivets on the back and a sturdy chipboard core, it incorporates a high percentage of post-consumer materials.
