Choosing fountain pen paper & notebooks comes down to a practical trade-off: do you want a compact ruled journal that travels easily, or a larger notebook built around smooth paper and a structured grid? The Sand ruled pocket notebook and the Tomoe River notebook take those different approaches. The clearest choice depends on whether portability and page organization matter more than format and paper feel.
Quick verdict
Choose the NEW - Journal Notebook in Sand Color Ruled Pocket Size - Fountain Pen Friendly for a pocket-oriented journal with ruled pages, numbered pages, and useful extras. Choose the Tomoe River Notebook 5.85x8.27\" 160 pages (80-Sheet) 5mm-Squared Grid White for a larger writing surface, 5mm graph layout, and thin, smooth Tomoe River paper. The price difference is $17.05, so the second choice makes the most sense when its paper and grid are central to your writing routine.

Where each product wins
The Sand notebook wins for portability and everyday journaling
Its pocket-size format, ruled layout, and 185 numbered pages make it easy to use as a compact journal, idea book, or organized daily notebook. Two page markers, a pocket, a sticker, and detachable pages add practical structure without changing the notebook's straightforward ruled format.
The Tomoe River notebook wins for grid-based writing
The 5mm-squared layout suits diagrams, neatly aligned notes, tables, and writing that benefits from consistent spacing. Its 5.85 x 8.27-inch format also provides a larger page footprint than the Sand notebook's pocket dimensions. The thin, velvety smooth paper is specifically suited to fountain-pen and ink-pen writing.
Product notes
NEW - Journal Notebook in Sand Color Ruled Pocket Size - Fountain Pen Friendly

The Sand notebook is the more convenient pick for a fountain pen journal that needs to stay compact. Its ruled A6 format supports ordinary paragraph writing, while 185 numbered pages make longer-term organization easier. The faux leather cover, two page markers, expendable pocket, sticker, and detachable pages give it several built-in journal features. It is also marked fountain-pen friendly, with 80 g/m² paper. The limitation is the pocket footprint: the 5.91 x 3.55 x 0.5-inch dimensions leave less room for wide handwriting, diagrams, or generously spaced notes than a larger notebook. The ruled format is also a specific fit for linear writing rather than grid-based planning.
Tomoe River Notebook 5.85x8.27\" 160 pages (80-Sheet) 5mm-Squared Grid White

The Tomoe River notebook is aimed at writers who want the paper itself to be part of the fountain-pen experience. Its thin, velvety smooth paper and 5mm-squared grid create a distinct setup for ink writing, structured notes, diagrams, and measured layouts. The larger 5.85 x 8.27-inch format gives those layouts more working space, while the black soft cover and thread-bound construction keep the design focused on the notebook rather than added accessories. Its main limitation is the grid: writers who prefer uninterrupted ruled lines may find the 5mm squares more visually structured than they want. The 160-page, 80-sheet format is also different from the Sand notebook's page count.
Final choice by use case
- For commuting, quick journaling, or a smaller desk footprint: choose the NEW - Journal Notebook in Sand Color Ruled Pocket Size - Fountain Pen Friendly. The pocket dimensions, ruled pages, and numbered-page system directly suit portable daily writing.
- For diagrams, planning, and carefully aligned notes: choose the Tomoe River Notebook 5.85x8.27\" 160 pages (80-Sheet) 5mm-Squared Grid White. The 5mm grid and larger page format are the more relevant attributes.
- For a straightforward fountain pen journal: the Sand notebook is the simpler fit because its ruled layout and journal extras are clearly defined.
- For prioritizing thin, smooth paper: choose the Tomoe River notebook, whose paper description centers on that texture and fountain-pen use.
In short, the Sand notebook is the practical compact journal, while the Tomoe River notebook is the more specialized choice for grid-based writing and a smooth paper feel.
