RETTACY Graph Paper Notebook B5 2-Pack - Thick 100 GSM Grid

In this review of the RETTACY Graph Paper Notebook 2-pack, the bottom line is straightforward: students, engineers, and bullet-journalers who need reliable, bleed-resistant grid paper will appreciate the pack for its paper quality and practical size. The notebooks are B5 (7.6 in x 10 in), come as a twin-pack with 160 pages per book, and the single biggest reason to buy is the 100 GSM acid-free paper that lets users write and sketch on both sides without ghosting or bleed-through.

Key Features

• B5 2-Pack: Two medium-size notebooks provide a total of 320 pages so there is plenty of space for notes, problem sets, and projects.
• 5 grids per inch: The precise 5 mm grid gives consistent alignment for math, engineering diagrams, graphs, and tidy bullet journaling.
• 100 GSM paper: Thick, acid-free sheets reduce bleed-through and improve durability so ink and pencil stay crisp and preserved.
• Twin-wire binding: Sturdy spiral binding lays flat at 180 degrees for easy drafting and comfortable writing across the spread.
• Flexible plastic cover: A transparent, waterproof cover protects notes from spills and everyday wear while keeping the notebook lightweight.
• Versatile use: The grid layout works equally well for students, technical sketches, data visualization, and organized note-taking.

Who It's For

The RETTACY grid notebook is best for high school and college students, engineers, and anyone who uses graph paper for math, physics, or schematic sketches; the medium B5 size balances portability with enough page area for diagrams. Artists and bullet-journal enthusiasts who prefer a rigid grid for layouts will also find the notebooks helpful because the paper handles most pens and markers without ghosting.

Those who need specialty paper types, such as heavyweight watercolor stock or perforated tear-out pages, should look elsewhere, since this product focuses on sturdy, standard 100 GSM graph sheets rather than specialty formats or larger engineering sizes.

Pros & Cons
