KOKUYO Campus Notebook 5-Pack, 5-Color Assorted, B5

This smart Campus notebook has evolved to be even easier to use and more environmentally friendly. It features a spine made of a special film laminate. Not only is the spine tear-resistant, but you can also write on it with a ballpoint pen. The highly functional cover design includes spaces for writing titles and names. Triangular markings are placed at the center and both ends of the page to help you draw accurate vertical lines. Additionally, markings are placed in the middle of the ruled lines so you can draw lines even with a short ruler. This is an environmentally friendly product that uses FSC-certified paper for its inner pages.Source: https://www.amazon.co.jp/
