STALOGY Editor’s Series Diary 2026 – B6 Slim Monthly (Dec 2025 Start)

Keep your monthly plans slim, simple and always with your notebook.

The Nitoms STALOGY Editor’s Series Diary 2026 – B6 Slim Monthly (SS0143) is a minimalist monthly planner insert created to sit neatly inside your A5 or B6 notebooks. Its B6 Slim size (121 × 182 mm) matches the height of A5/B6 but trims 7 mm from the width, so it won’t stick out when tucked into a STALOGY 365 Days Notebook or 1/2 Year Notebook. 

The diary covers December 2025 to March 2027, giving you plenty of overlap before and after the year. Inside you’ll find:

• Cover: 1 page
• Annual spreads for 2026 & 2027: 4 pages (2 spreads)
• Monthly block pages: 32 pages
• List-Up Pages: 6 pages for tasks, goals and project lists
• Grid Free Pages: 5 pages for notes, sketches or additional logs
• Total: 48 pages 
  

The monthly pages are block-style with a light grid and a subtle center line, making it easy to divide each day in two (e.g., AM/PM, work/private, schedule/todo). The grid keeps handwriting neat and makes it simple to draw extra lines, trackers or icons without clutter. 

STALOGY uses high-quality 81.4 g diary paper that balances thinness with resistance to show-through, so it works well with pencils, ballpoint pens and even many fountain pens. The overall notebook stays slim and lightweight, ideal for people who want to add monthly planning to their existing notebook instead of carrying a bulky planner. 

The cover is simple and modern, with two color options—Black and Gray—to match minimal work setups or cool stationery aesthetics. Designed as part of the STALOGY Editor’s Series, this slim monthly diary is perfect for students, professionals and creatives who love Japanese stationery and want a clean, functional monthly overview that travels inside their notebook.
