Choosing fountain pen paper & notebooks often comes down to one practical tension: do you want a structured page that keeps journaling orderly, or paper whose feel is the main attraction? The MD A5 Grid Ruled Notebook and Tomoe River Notebook take different approaches, so the right choice depends on whether layout, writing comfort, paper character, or price leads your decision.
Quick verdict
The MD A5 Grid Ruled Notebook is the lower-priced route to a clearly structured journal, while the Tomoe River Notebook is aimed at shoppers who prioritize a thin, smooth paper experience. The $17 listed-price spread makes the choice straightforward: pick MD when layout and cost come first; pick Tomoe River when paper feel is the centerpiece.
Compact comparison
| Comparison | MD A5 Grid Ruled Notebook | Tomoe River Notebook |
|---|---|---|
| Price | USD 22.99 | USD 39.99 |
| Format | A5 grid-ruled notebook | 5.85 x 8.27-inch notebook with 160 pages (80-sheet) |
| Grid | 5mm ruled grid | 5mm squared grid on white paper |
| Paper character | Bleed-resistant paper | Thin, velvety smooth Tomoe River FP paper |
Both notebooks use a 5mm grid dimension, but the page treatment is different: MD uses a ruled grid with light blue lines, while Tomoe River uses a squared graph layout. That distinction matters more than the shared measurement if you have a particular journaling style.
Where each notebook wins
- MD A5 Grid Ruled Notebook: The flexible binding opens 188 degrees, giving it a concrete advantage for an open-writing setup. It is the more natural fit for users who want the notebook to stay broadly open while they write.
- Tomoe River Notebook: Its clearly stated 5.85 x 8.27-inch size and 160-page, 80-sheet format make it the stronger match when you want a defined page package for a fountain pen journal.
Product notes
MD A5 Grid Ruled Notebook

The MD A5 Grid Ruled Notebook suits journaling that benefits from visual cues without a busy page. Its light blue lines are designed to stay subtle, and markers every five squares help with counted layouts or neatly spaced entries. The bleed-resistant paper is another concrete reason to choose it for fountain pen writing. The main limitation is the format named for the notebook: it is an A5 grid-ruled design, so shoppers specifically seeking the Tomoe River notebook's separately defined page package may find the other option a closer fit. For a lower-priced journal with a restrained layout and flexible construction, MD is the more direct choice.
Tomoe River Notebook

Tomoe River Notebook is suited to writers who want the notebook's paper and construction to feel central to the experience. The classic black soft cover and thread-bound format give it a traditional presentation, while the New Sub-Dot Grid creates a precisely defined 5 x 5 mm graph pattern. That makes it a concrete choice for fountain pen users who enjoy squared layouts and a distinctive notebook format. Its limitation is equally clear: the 5mm squared grid may not suit someone who specifically prefers ruled lines. Rather than a general-purpose layout, this notebook asks you to embrace its graph-paper format and Tomoe River identity.
Final choice by use case
Choose the MD A5 Grid Ruled Notebook for a structured, open-writing journal where the A5 Grid Ruled format and 188-degree opening match your routine. Choose the Tomoe River Notebook when thin, smooth paper and a classic black soft-cover presentation matter more than keeping the listed price lower. Both are Japan-made notebooks, but their page styles give them distinct roles for fountain pen writing.
