Writing pads feature Letr-Trim perforation at the top for a clean tear-out every time. Binding at the top is double-stitched for added strength. Sturdy, 60 point chipboard backer provides writing support and durability when you are away from your desk. Each letter-size pad contains 100 sheets of heavyweight, 16 lb. paper that resists bleed-through. Each sheet is legal/narrow-ruled with 1/4" line spacings and a 1-1/4" left margin.
