Starting with everything you love in a composition book, sturdy covers with a traditional marble design, Roaring Spring® Signature Collection Composition Notebooks take things a few steps further, adding rounded corners, a lay flat spiral-coil binding and heavier weight perforated pages to deliver a premium choice for serious students. Coil-locked spiral binding allows the book to lay flat when open while preventing snags on bags and clothing, and the heavier weight microperforated sheets help ensure clean separation while minimizing the potential for ink bleed through.
