Choosing fountain pen paper & notebooks is a format decision as much as a paper decision: do you want a lower-priced A5 notebook centered on fountain-pen-friendly paper and flexible page styles, or a more specifically defined 160-page, 5mm-squared grid? Both use Tomoe River paper, but the right choice depends on whether layout flexibility or a named page count and grid matters more.
Quick verdict
Pick the A5 Notebook when a lower listed price and a flexible writing setup matter most. Pick the Tomoe River Notebook when you want a named page count and square grid. The listed-price gap is $23.43, so the format difference-not fountain-pen suitability-should decide.

Product notes
A5 Notebook - 68gsm Tomoe River Paper

The A5 Notebook suits shoppers who want a fountain-pen-friendly notebook at a lower listed price. Its smooth, lightweight 68gsm Tomoe River paper resists bleed-through and feathering, giving it a clear role for fountain pen writing. The white paper cover and thread binding are concrete construction details, while the 5.8 × 8.3-inch format keeps the notebook within the named A5 size. The limitation is format specificity: its available styles span dot grid, ruled, plain, grid, and planner layouts rather than centering on the 5mm-squared grid named for the Tomoe River Notebook. Choose A5 Notebook when the $16.56 price and flexible writing setup matter more than a fixed square grid.
Tomoe River Notebook - 160 Pages, 5mm-Squared Grid

Tomoe River Notebook is the format-led choice for shoppers who want a clearly specified writing grid: 160 pages, or 80 sheets, with 5mm-squared ruling. Its white pages, classic black soft cover, and thread binding establish a defined notebook setup, while Japanese Tomoe River paper is smooth for fountain pens and ink pens. The limitation is cost: at $39.99, it sits $23.43 above A5 Notebook. Its grid-led format is less natural for someone seeking A5 Notebook's broader mix of dot grid, ruled, plain, grid, and planner styles. Choose Tomoe River Notebook when the named page count and square ruling matter more than the lower listed price.
Final choice by use case
- Everyday notes, sketches, or mixed planning: Choose A5 Notebook. Its lower listed price and range of named page styles make it the more adaptable direction.
- Grid-led notes and square planning: Choose Tomoe River Notebook. The 160-page, 5mm-squared-grid specification makes its intended format unmistakable.
- If paper behavior is decisive: Choose A5 Notebook for the explicit fountain-pen-friendly wording and stated resistance to bleed-through and feathering.
- If cover style matters: Choose Tomoe River Notebook for its named black soft cover, or A5 Notebook for its white paper cover.
