An ingenious encounter between paper and pen. This is a flat-bound notebook from the PERPANEP series. A perfect-bound double-page binding that eliminates unevenness when opened. Uses original rough paper that provides a rough writing feel, yet allows the pen to move with a light touch without sinking. The surface is intentionally left rough, giving the paper a firm finish throughout, allowing you to feel the rough texture of the pulp fibers with your fingertips, while still providing a light and calm writing feel. Ink shades are clearly visible, allowing you to enjoy the texture of letters and lines. (Because the paper surface is very rough, lines written with pencil or mechanical pencil tend to be dark.) 4mm grid lines allow for balanced writing and drawing. **Reseller Disclaimer: Kokuyo items cannot be sold on Amazon, eBay, or Walmart.com.**
