Writing pad features an emerald green top binding, extra-rigid backboard and 16 lb. sheets. 80 point chipboard backer delivers superior stability and extra writing support when you are away from a desk. Heavyweight, 16 lb. paper resists bleed-through. Letr-Trim perforations assure clean and easy sheet removal. Letter-size pad is three-hole punched to fit in standard three-ring binders and double-stitched at the top for added strength. Each pad contains 100 sheets. Each sheet is college-ruled and has a margin.
