Life Margin Notebook - A5 - Ruled. Life Margin notebooks were named "Margin" because each page in the notebook comes with a pink margin that runs down the page at 1.4 in (3.5 cm) from the left side of the page. Visually, the pink margin and the 6mm blue lines on the page may remind you of the looseleaf and composition paper that students use, but after feeling the paper, you will realize the paper in this notebook is far superior. Life Margin notebooks come with Life's own "L writing paper white." The paper is smooth to the touch with a nice thickness, and will allow you to use fountain pens, gel pens, broad rollerball pens and pencils on it. Each notebook comes with 80 sheets of paper, a flexible Kraft paper cover, and has a front page with a designated section for you to use as an index. We love the retro look of this notebook, the letterpress branding on the cover and the pops of bright color used on the spine and cover of each book.
