Where each notebook wins
A5 Notebook with Tomoe River Paper
This is the stronger fit when your notebook needs to handle different kinds of work. The listed layouts cover planning, notes, sketches, and more structured writing, while the Tomoe River paper gives fountain pen users a clear paper-specific reason to choose it. Its 5.8 × 8.3-inch format and thread-bound construction also match the description's everyday-carry focus.
MD A5 Grid Ruled Notebook

The MD notebook wins when a consistent visual framework is the priority. Its 0.2-inch (5mm) grid, light blue lines, and markers every five squares provide a defined structure for handwriting, diagrams, or measured layouts. The description also says its binding opens 188 degrees, which supports the notebook's writing-focused design.
Product notes
A5 Notebook with 68gsm Tomoe River Paper

The A5 Notebook with 68gsm Tomoe River Paper is the adaptable choice for a fountain pen journal that may shift between tasks. Its description names dot grid, ruled, plain, grid, and planner layouts, while the paper is described as smooth, lightweight, acid-free, and resistant to bleed-through and feathering. The 5.8 × 8.3-inch size and thread-bound construction support its portable format, and it is designed as a refill for the Field Journal and Field Folio A5. The limitation is that its appeal depends on selecting among multiple layout styles; unlike the MD notebook, it is not centered on one dedicated 5mm grid format. Choose it when Tomoe River paper and layout flexibility matter most.
MD A5 Grid Ruled Notebook
The MD A5 Grid Ruled Notebook is the focused choice for shoppers who want a consistent grid for writing or sketching. Its title and description specify a 0.2-inch (5mm) grid, light blue lines, markers every five squares, and a binding that opens 188 degrees. The paper is described as bleed-resistant, and the binding and design are said to promote writing comfort. Those details give it a clear grid-led identity rather than the multi-layout approach of the Tomoe River notebook. Its limitation is equally specific: a fixed grid may be less suitable when your plans call for plain, ruled, dot-grid, or planner pages. Choose it when repeatable grid structure is more important than layout variety.
Final choice by use case
Choose the A5 Notebook with Tomoe River Paper for flexible journaling, mixed notes, planning, or a fountain pen-friendly notebook where paper type is central to the decision. Its range of stated layouts gives it broader use across writing projects.
Choose the MD A5 Grid Ruled Notebook for grid-led handwriting, sketching, or page designs that benefit from light blue 5mm spacing and markers every five squares. If the $6.43 gap matters and you do not specifically need a fixed grid, the Tomoe River notebook makes the clearer choice; if the grid is the reason you are shopping, the MD format is the better match.
