The Hobonichi Techo is a Japanese daily planner, and it prints each month of the year in its own soft colour. TSUKI no IRO, the colours of the moon, is Hobonichi's stationery series built on those same twelve colours.

That is the whole idea. A sticker from this range already matches the page it lands on. Stay with the month's own colour to keep a page calm, or borrow another month's colour as a code for work, travel or birthdays.

Why people love it

• Each set carries all twelve monthly colours, so one pack covers a whole year
• The clear pieces are printed on sturdy transparent PET film, so the date and the grid still read through the colour
• Sizes follow the Techo's own grid squares and monthly calendar columns, so nothing needs trimming
• Plain shapes and colour, no characters, so they sit under your own handwriting rather than competing with it

Between round dots, index tabs, frames and translucent notes there is a piece here for tracking a habit, flagging a month or simply making a page look good.
