Midori Paintable Stamp Half Size: Pre-Inked Planner Stamp
The Midori Paintable Stamp Half Size is a pre-inked planner stamp: the black oil-based ink sits inside it, so you stamp without a pad and then color over the print with water-based markers.

What is the Midori Paintable Stamp Half Size?
It’s a small pre-inked stamp from Midori’s Paintable Stamp line: the ink is already inside, and the print is meant to be colored in. Each stamp carries one design, from a time tracker to a little cat.
Midori is the stationery brand of Designphil Inc. in Tokyo, and the Time Tracker’s item number is 35511006. JetPens, Paperwhisper and Circle Tape carry the Half Size designs in the US and Hong Kong.
Midori Paintable Stamp Half Size specs

All figures come from Midori’s Japanese online store. Print sizes aren’t published for each design; the full-size stamp’s picture is about 50 mm square on a 61 mm body, so a Half Size print is likely around 50 × 25 mm. That’s our inference, not a Midori figure.
What does “half size” mean?
It’s half the footprint of a full-size pre-inked Paintable Stamp. Midori gives the full-size stamp as 61 × 61 × 19 mm, and the Half Size body is 61 × 30.5 mm; Midori says two Half Size stamps side by side stack on a square one for storage.
In practice, a Half Size print fits a single day in a weekly planner or a margin of a daily page. A full-size stamp fills a sticky note or a larger block.
How does a pre-inked Paintable Stamp work?
You press it straight onto the page; the black oil-based ink is held in the stamp, so there’s no pad. Midori says one filling lasts about 1,000 prints, and its refill ink tops it up when the print fades. Its rectangular shape is meant to be easy to press with one hand.
Once the print is down, you color it with water-based markers. Midori says the oil-based ink won’t bleed under them, which is why it calls the line “Paintable”. Little Craft Place advises a quick, light press rather than holding it down, to stop excess ink.
Which Half Size design should you choose?
Pick a functional design if you track time or tasks, and a decorative one if you just want color. Midori’s Japanese store lists ten Half Size designs, item numbers 35504006 to 35513006:
| Use | Designs |
|---|---|
| Planning | Time Tracker, Vertical, To Do List, Today’s Comment |
| Tracking | Weather |
| Decoration | Cat, Flower, Seal, Stationery, Bear Speech Bubble |
Midori says the Time Tracker suits logging times, study hours or sleep, and the Vertical design lets you manage a day’s schedule just by stamping it. Health Management and Money designs that some US shops list belong to Midori’s full-size pre-inked range.
Which markers work over it?
Any water-based marker or highlighter should work, according to Midori and retailers. A soft highlighter such as the Zebra Mildliner is a common choice.
The stamps suit smooth planner paper such as the Midori MD Notebook and the Hobonichi Techo Original. If you want the date to change from day to day, see the Midori Paintable Rotating Date Stamp.
What are the downsides?
Each stamp prints one fixed design in black, so you need a separate stamp for every layout. There’s no date to change and no ink color to swap; for a changing date, the rotating stamp does that job.
Midori doesn’t publish the print size of each design, so measure against your planner before buying several. Midori also warns that drying can be slower, and the ink can spread, on some papers, and says the full-size stamp may bleed through depending on how hard or long you press, so test it on the back of a page first.
Where is it made?
Midori’s Japanese online store lists the Half Size Paintable Stamps as made in China. The Time Tracker, Cat, Vertical and To Do List pages all give MADE IN CHINA.
Midori is a Japanese brand of Designphil Inc., based in Tokyo.
