Maruman Mnemosyne B5 Spiral Notebook - 7mm Lined - Black

The Maruman Mnemosyne B5 Notebook – 7mm Lined is designed with a more structured, professional style compared to typical notebooks. The B5 size gives you more writing space than A5 while still staying portable, and the clean black cover with minimal branding keeps the overall look understated and practical.

Inside, the notebook uses smooth 80 gsm Japanese paper with a 7 mm ruling, which is slightly wider than standard lines and works well for neat, readable writing. The lines are printed in soft grey, and every page includes a title and date section at the top, along with two slightly bolder horizontal lines that divide the page into sections—helpful for organizing notes or separating ideas.

The notebook contains around 80 micro-perforated sheets, making it easy to tear out pages cleanly when needed. The twin-ring binding allows it to lay flat while writing, and the paper is acid-free and known for handling fountain pens well with minimal bleed-through, which makes it a reliable choice for daily writing or work notes.
