Graph Paper Notebook B5 Grid Spiral Notebook - Durable Leather Cover

Our review of the RETTACY Graph Paper Notebook finds it best suited for students, engineers, and note takers who need a reliable, medium-size grid journal for precise work. The single biggest reason to buy is the combination of 100 GSM acid-free paper and a sturdy leather hardcover, which together minimize bleed and protect pages during daily use. This notebook strikes a practical balance between portability and usable writing space in a B5 (7.6in x 10in) format, making it a solid choice when clarity and longevity matter.

Key Features

• B5 size: The 7.6in x 10in format gives more room than A5 without being bulky, useful for sketches and extended notes.
• 100 GSM paper: Thick, acid-free pages reduce ghosting and bleed-through so pens and markers stay cleanly on the page.
• 5 mm grid: The 5 mm spacing creates consistent structure for math, engineering sketches, and neat planning.
• Leather hardcover: A smooth leather cover protects pages and gives the notebook a durable, premium feel for everyday carry.
• Twin-wire spiral: The sturdy spiral binding lies flat for more comfortable writing across both pages.
• Organization extras: Built-in pen holder, elastic closure, inner pocket, ribbon bookmark, ruler and sticky index tabs keep notes organized and accessible.

Who It's For

This notebook is ideal for students, engineers, architects, and hobbyists who need a dependable grid format for calculations, diagrams, and precise sketches. The thicker 100 GSM sheets make it a good match for those who use a variety of pens and want to avoid bleed and ghosting while preserving notes long term.

Those who prefer pocket-size notebooks or require very large sketchbooks should look elsewhere; the B5 medium size is a compromise between portability and workspace rather than a travel pocket or studio pad.
