Why the STALOGY Slim Monthly Diary is Special
If you’ve ever tried to slip a planner into your notebook but hated how it stuck out, you’re going to love this one. The STALOGY Slim Monthly Diary comes in two sizes, A5 Slim and B6 Slim, and both are designed to fit neatly into your STALOGY 365 Days Notebook or 1/2 Year Notebook. The height stays the same, but the width is trimmed by 7mm so the edges don’t peek out. Neat and tidy, just the way stationery lovers like it.
It’s lightweight, easy to carry, and comes in two classic colors: black and gray.
Unique Features You’ll Love
1. Slim Size for a Perfect Fit
No more messy edges or awkward overhangs. The slim shape slips right into your notebook so you can carry both together without adding extra bulk.

2. List-Up Pages for Life Logging and To-Dos
This 2026 edition adds 6 new List-Up Pages that help you keep track of tasks, goals, and wish lists. You can log your daily habits, track progress, and check off tasks as you go. Perfect for life log diary fans or anyone who loves to-do list planners.

3. Split Your Day with Center Lines
Each daily box in the monthly view has a center line so you can divide your plans. Morning and afternoon? Work and personal? Your schedule and your family’s? You decide.
4. Handy Grid Layout
The A5 Slim comes with a 4mm grid and the B6 Slim with a 5mm grid. These grids guide your writing and are great for placing stickers like STALOGY masking circle stickers.
