The Fabriano Layout Pad paper has an exceptional ability to take all felt pens and markers (even alcohol based). The 8.25" x 11.75" and 11.75" x 16.50" pads hold 70 sheets of acid-free, light-weight 75gsm (40 lb.) slick extra-white paper that is completely bleed-proof thanks to its proprietary sizing. The paper is ideal for calligraphy and sketching, as well as technical and graphic drawing, but its weight also makes it suitable for tracing.
