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. 60 point, rigid chipboard backer provides writing support and durability. Each pad contains 50 stitched sheets of heavyweight, 16 lb. paper that resists bleed-through. Each sheet is legal/wide-ruled with 11/32" line spacings and a 1-1/4" left margin.
