Coated plastic covers fold back over the rings to lie flat on surfaces for easy note-taking. 1-1/2" rings hold up to 300 sheets of paper. NoteProtector dividers protect your important papers when stored. Notebook comes pre-filled with 30 quad-ruled sheets and 70 college-ruled sheets of letter-size paper.
