Pacon Dual Ruled Composition Books feature two alternating ruling styles. The right-hand page offers a 3/8" wide ruling for traditional note taking and the left-hand page features a 1/4" grid ruling to draw coordinating graphs, illustrations, and interpretations. Note taking in this manner engages both hemispheres of the brain. These durable, hard cover, one-subject books are available with gray colored covers and white paper on the inside. The colors also allow students to organize by class, theme or semester. Recyclable. About us: Pacon is part of the Dixon Ticonderoga family of products which teach, learn, and create.
