What are Hobonichi Transparent Dot Stickers?

They are small round stickers of tinted, clear PET plastic that Hobonichi sells for marking and color-coding its Techo planners. In Japanese they’re シースルー丸シール (see-through round stickers), part of TSUKI no IRO (“colors of the months”), a line built on the 12 calm colors used in the Original, Cousin and HON books.

Because the plastic is transparent, a dot can sit over a date, a grid square or a word and still let it show. Hobonichi says the three sizes are made to sit comfortably in the grid of the Hobonichi Techo Original and its other planners.

Hobonichi Transparent Dot Stickers drawn to scale over a 3.7 mm grid: a 3.5 mm dot fits one square, a 6 mm dot about 1.6 squares and a 15 mm dot about 4 squares; 576, 192 and 48 dots per set — The three dot sizes against the Techo Original's 3.7 mm grid.

Which size should you choose?

Pick 3.5 mm for checklists and habit trackers, 6 mm for highlighting or sorting, and 15 mm for pinning a memo or decorating a page. Those are the uses Hobonichi suggests for each size.

Size	Grid squares it covers	Good for
3.5 mm	1 square on the 3.7 mm daily grid	Bullets, habit dots, color-coding lines
6 mm	About 1.6 squares	Marking a date on the monthly calendar
15 mm	About 4 squares	Circling a whole day number or a heading

On the monthly calendar pages, whose grid is 3.45 mm, a 3.5 mm dot is very slightly wider than one square. The 3.5 mm set gives the most dots per yen, at 576.

What are the 12 colors?

The 12 colors are Hobonichi’s TSUKI no IRO month colors, one for each month of the year. In The Journal Shop’s English names, January to June are Mandarin Orange, Brown Black, Plum Purple, Poppy Red, Avocado Green and Green Black; July to December are Nemophila Blue, Blue Black, Cappuccino Brown, Violet, Emerald and Red.

Every set has all 12 colors in equal numbers, so you can give each month, person or project its own color. The same names appear on other TSUKI no IRO items, such as a set of uni-ball One gel pens.

Can you write on or through the dots?

You can read through them: the dots are tinted clear PET, so the grid and handwriting underneath stay visible. Hobonichi doesn’t say which pens write on top of the plastic. PET is slick, so ink from water-based pens may bead or smear.

How do they compare to other Hobonichi stickers?

The dot stickers are the plainest, most functional Hobonichi stickers: color, not pictures. The other everyday Techo add-on is the Hobonichi Pencil Board, a 0.4 mm sheet that goes under the page you’re writing on.

Hobonichi sticker	What you get	Material
Transparent Dot Stickers	48 to 576 round dots, 2 sheets	Clear PET
TSUKI no IRO Sticker Set (Schedule)	5 sheets of 148 × 100 mm, including icon stickers	Paper
Frame Stickers	81 frames on 4 sheets, for writing inside	Tracing paper

For dating undated pages, the Frame Stickers for Dates pack holds 100 see-through frames on 5 sheets.

For illustrated stickers, washi sheets such as Midori Yuru Log stickers are removable and printed with small animals and flowers. Loose flake stickers such as Mind Wave Washi Flowers come 40 to a pack, each about 1 in across. US sticker books such as Happy Planner value packs carry hundreds of stickers per book but are sized for larger planners.

Where are Hobonichi Transparent Dot Stickers made?

Luiban gives Japan as the country of origin. Hobonichi is based in Tokyo, but its Japanese and English store pages don’t state where the stickers are made.
