■Starting December 2025 (14 months worth),
the slim and lightweight MD Notebook Diary <A5> Slim is a variation of the MD Notebook Diary A5. It combines a flexible monthly block format with grid-ruled notes.

MD paper offers excellent writing comfort and prevents bleed-through, even with a fountain pen. Sewn and bound flat, it's a simple, high-quality diary whose streamlined design takes advantage of the quality of the material and inspires the user's creativity.
MD paper is used not only for the main text but also for the cover and endpapers, ensuring the ultimate writing experience.

The monthly block has plenty of white space and is highly flexible. The spacious white space can be used freely for illustrations, notes, etc. You can enjoy filling in the white space with your daily feelings, ideas, and things that strike a chord with you.

Grid-ruled memo pages allow for neat writing and drawing, and are convenient for jotting down notes, ideas, to-do lists, and more. The light blue 5mm grid squares won't interfere with your writing or sketching.

Comes with a sticker that can be used as a label or bookplate. The included label can be used to distinguish it from regular MD Notebooks. It also serves as a reinforcement for the bookmark string.
