These wire-bound notebooks are perfect for science classes, doodles or just note-taking. Smooth, white, 15 lb. writing paper is college-ruled. Ends of the spiral wire are coil-locked for snag-proof performance. Covers are printed on a bright board and come in assorted colors. Each notebook contains perforated paper and is three-hole punched along the binding edge so it can easily fit inside letter-size, three-ring binders.
