Paper that shows what your ink can actually do

Most notebooks compromise the ink to protect the paper. Logical Prime doesn't. The 75gsm surface is smooth enough to show the colour variation and secondary sheen effects that make specialist inks interesting, while the paper weight and coating are calibrated to dry faster than slow-absorbing papers like Tomoe River. The result is ink that looks genuinely alive on the page — shading visible, sheen present in pooled areas — without the slow dry times that frustrate left-handed writers or anyone who works quickly. Standard fountain pen inks, including wet-flowing inks tested with No.8 nib grades, perform without feathering or bleed-through.

The ruling and format

Logical Prime uses a Séyes-influenced ruling — a primary line with a lighter guide line above, familiar to anyone who has used French school notebooks or Clairefontaine. The header at the top of each page provides space for date and contents reference, making individual pages easy to locate. Pages are numbered. The thread binding holds the notebook completely flat when open, which matters for anyone using a dip pen or writing across the full width of a spread.

Honest Note:

Blank ruling is not currently available in the Logical Prime range — the four rulings are 6mm lined, 7mm lined, grid, and dot. Each cover colour corresponds to a specific ruling. At 40 sheets (80 pages) the thread-bound notebook is slim — if page count matters more than flatness, the spiral-bound version offers 50 sheets. Pigment inks with elevated particle loads (including some Kakimori colours) may feather on this paper.

Who is it For?

Fountain pen users who want a slimmer, faster-drying alternative to Tomoe River notebooks
Writers and note-takers who want well-ruled pages that handle fountain pen inks without compromise
Art journallers who want to see ink shading and sheen without committing to loose sheets
Anyone who works with Teranishi Guitar, Dominant Industry, or Pilot Iroshizuku and wants to see those inks perform

FREQUENTLY ASKED QUSTIONS (FAQ)

How does Logical Prime paper compare to Tomoe River?

Tomoe River is thinner (52gsm) and slower-absorbing, producing more dramatic shading and sheen but with longer dry times. Logical Prime at 75gsm dries faster and handles wetter nibs more reliably, while still showing shading and sheen clearly. For daily writing, Logical Prime is more practical; for ink testing and appreciation, Tomoe River is more dramatic.

Can I use a dip pen in a Logical Prime notebook?

Yes — the thread binding means the book lies completely flat, which is necessary for comfortable dip pen use. The paper handles dip pen inks including waterproof drawing inks well, though for dedicated illustration work loose sheets or a sketchbook designed for heavier media may be more appropriate.

What is the difference between the A5 and B5 sizes?

A5 is 148 × 210mm — the standard notebook size, slim enough to carry. B5 is 182 × 257mm — a larger format suited to spread writing, detailed notes, or anything that benefits from more horizontal space. Both use the same paper and rulings.
