Three-ring binder is perfect for presentations, organizational projects, office reports, class projects, and more. The cover is made from strong vinyl and is tightly sealed over rigid chipboard. Spine-mounted, 1" round rings with double boosters can hold up to 200 letter-size sheets of letter-size paper with ease. It also includes two clear inside horizontal pockets for additional storage and organization of loose documents and non-punched papers. Each pocket provides enough space to hold notes, photos, business cards, or full-size pages that will be hole-punched later.
