The OEM Pacon Dual Ruled Composition Book is designed for efficient and thorough note-taking. It features dual ruling, with right-hand pages having a 3/8" rule for traditional note-taking and left-hand pages being 1/4" grid-ruled for drawing graphs and illustrations. The hardcover protects your notes from rips and tears, while the durable binding ensures that pages are permanently bound to prevent removal. Additionally, a designated location for your name on the front cover allows for quick reference.
