The OEM Avery Durable Reference Binder AVE27351 is designed for frequent reference with its durable construction. It features wider front and back panels that fully cover standard dividers and sheet protectors, ensuring your paperwork remains protected. The Slant-D rings offer a higher page capacity compared to same-size round rings, allowing your letter-size pages to lie flat. With a 1-1/2 inch ring capacity, this binder accommodates approximately 375 sheets and includes two interior pockets, each holding up to 20 sheets. The design also incorporates exposed rivets on the back, a sturdy chipboard core, and a high percentage of post-consumer materials.
