Brand and Product Background
The notebooks are from Midori’s MD Notebook line, which focuses on a simple design to improve the writing experience. The MD paper, created in the 1960s, has been improved over the years to provide a smooth surface that works well with fountain pens.
Midori’s notebooks use thread-stitched binding, which lets the pages open flat to 180 degrees easily, without the stiffness common in glued or spiral notebooks.
MD Notebook A5 Overview
- Size: 14.8 × 21 cm (A5)
- Pages: 176
- Binding: Thread-stitched bookbinding
- Features: Bookmark string, label stickers, lay-flat opening
- Paper: High-quality MD paper, fountain pen-friendly

The MD Notebook A5 is designed with a minimalist aesthetic, featuring exposed cheesecloth mesh tape along the spine rather than a traditional cover. This intentional design choice favours simplicity and a tactile writing experience. A paraffin-paper wrap protects the notebook against dirt and handling.
MD Notebook A6 Overview
- Size: 10.5 × 14.8 cm (A6)
- Pages: 176

The MD Notebook A6 shares the same core characteristics as its larger counterpart but in a more compact footprint suited to everyday carry or on-the-go writing. Like the A5, its minimalist construction is intentionally free of a rigid cover, emphasising the feel and performance of the materials themselves.
Paper and Writing Experience
The MD Notebook line features specially designed MD paper by Midori. This paper has a smooth surface and works well with various writing tools, including fountain pens, without bleeding or feathering.
Because of the thread-stitched binding and paper quality, both A5 and A6 formats open flat, providing a stable writing surface whether at a desk or on the move.
The A5 size offers a traditional notebook experience with roomier pages, while the A6 provides a more portable option for field notes, lists, and quick entries.
