Each stamp is a block of wood with a rubber die on a cushion, the classic Japanese hanko format. You ink it on a separate pad, so one stamp can print in any colour. ## What does the Weekly Weather stamp print? **A design for logging the week's weather in a planner: its Amazon US listing calls it a "weekly weather date mark".** We haven't yet stamped it ourselves, so our cover shows a stand-in pattern rather than the real design. It's one of four 30 × 30 mm designs, 0412-001 to 0412-004. Kodomo no Kao's page shows each design in use, so check the image there for the exact layout before buying. ## How big are #Techo Hanko-bu stamps? **They come in six sizes, from a 15 mm square to a 55 × 70 mm block, all 24 mm tall.** ![The six #Techo Hanko-bu stamp sizes drawn to scale, 15 × 15 mm to 55 × 70 mm, with the 30 × 30 mm Weekly Weather size highlighted](https://stationerytimes.com/images/kodomo-no-kao-techo-hanko-bu-stamp-sizes.svg) *The six sizes at 1 mm = 2 px; Weekly Weather is the 30 mm square.* | Item numbers | Stamp size | Japan price, tax included | |---|---|---| | 0409-015 to 020 | 15 × 15 mm (0.6 in) | ¥748 (about US$4.70) | | 0411-001 to 003 | 50 × 20 mm (2.0 × 0.8 in) | ¥550 (about US$3.50) | | 0412-001 to 004 | 30 × 30 mm (1.2 in) | ¥605 (about US$3.80) | | 0412-005 to 007 | 60 × 15 mm (2.4 × 0.6 in) | ¥605 (about US$3.80) | | 0413-001 to 003 | 45 × 45 mm (1.8 in) | ¥748 (about US$4.70) | | 0414-001 to 005 | 55 × 70 mm (2.2 × 2.8 in) | ¥1,078 (about US$6.80) | ## Weekly Weather stamp specs | Spec | Value | |---|---| | Maker | Kodomo no Kao Co., Ltd. (Japan) | | Item | N #Techo Hanko-bu, Weekly Weather, 0412-001 | | Size | 30 × 30 × 24 mm (1.2 × 1.2 × 0.9 in) | | Construction | Wood holder, urethane cushion, rubber die | | Ink | None built in; use any stamp pad | | Japan price | ¥605 (about US$3.80), tax included | | Made in | China (Amazon US listing) | | Price band | $$$ ($20–75) as a US import | ## How do you get a clean print? **Ink lightly, press straight down with even pressure, and lift without rocking.** A 30 mm wooden block is easy to hold square, which helps on a planner page that doesn't lie flat. Over-inking fills in small lines, and rocking the block doubles the edges. On a thick planner, put a firm card under the page you're stamping, so the rubber meets a flat surface. If you stamp the same spot every week, a stamp positioner such as a [MISTI](https://stationerytimes.com/guides/misti-stamping-tool/) lines it up, though a small hand stamp rarely needs one. ## Which ink pad works best? **A fine-detail pigment pad for crisp lines, or a water-based dye pad if you'll colour the boxes in with markers.** [VersaFine Onyx Black](https://stationerytimes.com/guides/versafine-onyx-black-ink-pad/) is a common choice for small, detailed stamps, and [Memento Tuxedo Black](https://stationerytimes.com/guides/memento-tuxedo-black-ink-pad/) is the pad Tsukineko recommends for alcohol-marker colouring. Wipe the rubber clean when you switch colours, so the next print isn't tinted. ## How do these compare with Kodomo no Kao's button stamps? **#Techo Hanko-bu stamps are larger, single-design rubber stamps that need a pad; the Pochitto stamps are small self-inking buttons for tiny icons.** | Stamp | Type | Image | Price band | |---|---|---|---| | #Techo Hanko-bu Weekly Weather | Wooden rubber stamp | One 30 mm design | $$$ (US import) | | [Pochitto6](https://stationerytimes.com/guides/kodomo-no-kao-pochitto6-push-button-stamp/) | Self-inking, 6 buttons | 5.5 mm icons | $$ | | [Pochitto Pick!](https://stationerytimes.com/guides/kodomo-no-kao-pochitto-pick-stamp/) | Self-inking, removable | 6 mm icons | $$ | In Japan this stamp costs less than either Pochitto. In the US the only listing we found priced it as an import, which puts it in our $$$ band. ## Where are #Techo Hanko-bu stamps made? **In China, according to the Amazon US listing for 0412-001.** Kodomo no Kao's own #Techo Hanko-bu page doesn't state a country, and the maker lists its Pochitto6 self-inking stamps as made in China as well. ## Frequently asked questions ### What does Techo Hanko-bu mean?
