SAKAE TP iroful Notebook A5 5 mm Dot Grid White 96 Pages
The SAKAE TP iroful Notebook A5 5 mm Dot Grid White 96 Pages combines smooth 75 gsm iroful paper with an indigo dot grid and thread-sewn binding. Its portable format is well suited to fountain pen writing, journaling, planning, calligraphy, drawing and ink testing. The subtle ruling keeps notes organized while allowing ink color and tonal variation to remain the focus.
Made to Reveal Ink Color
iroful paper is designed to display saturated color, shading and crisp line definition. Its smooth, slightly cushioned surface also provides an effective setting for sheen and shimmer inks. The appearance and drying behaviour of each ink will vary according to the nib, flow and writing instrument, making the notebook useful for both everyday writing and more detailed ink exploration.
A 5 mm New Sub Dot Grid
The full-page 5 mm dot grid is printed in indigo using SAKAE TP’s New Sub Dot Grid system. Each visible dot is formed from a group of microscopic sub-dots separated by tiny spaces. This structure allows liquid ink to reach the paper when a stroke crosses the printed guide, helping the line remain clear instead of being visually interrupted by a solid dot.
The ruling provides enough guidance for handwriting, lists, layouts and planning while leaving space for sketches, diagrams and ink swatches. Its regular 5 mm spacing also makes it easy to divide the page into sections or develop a personal organization system.
Thread-Sewn Binding in a Portable A5 Format
Measuring 148 × 210 mm, the notebook contains 96 pages, or 48 sheets. Thread-sewn binding makes the pages comfortable to open and improves access to the area near the spine. The softcover construction keeps the notebook light enough for daily use while still providing a practical place to preserve writing, calligraphy exercises, drawings and ink records.

Frequently Asked Questions
Is this notebook suitable for fountain pens?
Yes. iroful paper is designed to present fountain pen ink color, shading and line definition clearly. It can also be used with glass pens, dip pens and calligraphy tools. The final result will always depend on the chosen ink, nib and ink flow.
What is the 5 mm dot grid like?
The indigo ruling covers the full page and uses the New Sub Dot Grid system. Each dot consists of microscopic sub-dots with small spaces between them, allowing the guide to remain visible without unnecessarily covering or interrupting the appearance of an ink stroke.
How many pages does it have and which ruling does it use?
The notebook contains 96 pages, equivalent to 48 sheets, of white 75 gsm iroful paper in A5 format. Every page features an indigo 5 mm dot grid.
How does iroful differ from Tomoe River FP?
At 75 gsm, iroful has a slightly more cushioned feel and a structure that minimizes show-through. It is designed for vivid color, shading, sheen and shimmer while maintaining crisp lines. Tomoe River FP is thinner and lighter, making it especially useful when a high page count is required in a compact notebook.
SAKAE TP and the Philosophy Behind iroful
iroful belongs to the paper paper range by SAKAE Technical Paper. “Iro” is the Japanese word for “color”, and the name plays on the idea of “colorful” to express the delicate shades and brilliance of fountain pen inks. The range explores how a writing surface can make the individual character of each color more visible.
SAKAE Technical Paper introduced iroful in 2021 as part of a project created to explore the expressive possibilities of paper and encourage the enjoyment of handwriting and drawing. The notebook format brings this philosophy to a portable and organized surface for preserving writing, drawings, calligraphy exercises and ink tests.
“A subtle grid can bring order to the page without limiting what the ink is free to express.”
