D-ring durable binder features a clear overlay on the front, back and spine to give you full control and flexibility over customizing presentations, organizational projects, office reports, class projects and more. Three-ring binder is packed and wrapped to create a custom reference system for weekly or monthly office reports, multiple classes at school or other unique personal or professional project binder. 6" binder with double boosters can hold up to 1,225 letter-size sheets with ease. Rings are mounted on the back lid to let pages lie flat and prevent wear-and-tear of the documents. It also includes two clear, inside horizontal pockets for additional binder storage and organization of loose documents and unpunched papers.
