Please read before you buy

This part matters. Please read it before ordering.

Prices include shipping within Japan.
Shipping usually takes 1–2 weeks.
The switches are Kailh Choc V2 (low-profile). Full-size switches such as Cherry MX do not fit — they hit the case.
Keycaps: 17 mm pitch, up to 16.5 mm wide. Common 18 mm-pitch Choc keycaps such as MBK (17.5 mm wide) do not fit.
The original keycaps are 3D-printed and made for the Kailh Deep Sea Silent Mini (Choc V2). Fit on other switches is not guaranteed.
The wireless microcontroller board used is the Japan radio-certified Seeed Studio XIAO nRF52840 (certification 211-220207).
Two config apps: a desktop app (Windows 10/11) and a browser app. The browser app also works on Mac — open it in Chrome or Edge and plug in USB.
Windows may show a blue SmartScreen warning when installing the app. Check that the file came from the buyers’ page, then follow the installation steps in the included build guide or start guide.
Privacy: the companion app (desktop and browser versions) collects and sends no data at all — no usage data, no personal data. Settings are stored only on your PC and in the keyboard itself.
The case and keycaps are 3D-printed. Layer lines (fine horizontal stripes), tiny bubbles and slight color differences are normal for a handmade item, not defects.
Each unit is made individually. If you would like a different color or a custom change, just ask the maker — it may be possible.
The bottom color of the case, the power switch, the color / design / material of the name plate, and the bonus engraved bunny keycap are whatever the maker chose that day. Please enjoy it as part of a one-of-a-kind item.
Initial-defect warranty: if it does not work and you contact us within 14 days of delivery, we repair or replace it free of charge. Returns or exchanges for other reasons are not accepted.
Homes with small children or pets: keycaps and switches are small parts that can come off. Keep them away from mouths.
About the battery: a lithium-polymer battery is built in (made by a battery maker, with a protection circuit). We check the lot inspection report and test each cell before installing it. Do not leave it in hot places (a car in summer), do not drop it hard, and stop using it if it swells. Dispose of it under your local rules for small rechargeable batteries.

FAQ

Tap a question to open it

How do I type numbers and symbols?

With "layers": hold one key and press another to get numbers and symbols. Together with letters, 30 keys cover everything. Once you get used to it, your hands barely move.

Is changing the settings hard?

A companion app is included (Japanese UI). There is a desktop app (Windows) and a browser app (Mac and others). Plug in the USB cable and it connects by itself. To remap a key, click the key on screen and press the key on the keyboard. Everything is saved automatically, and "Undo" lets you go back anytime.

Does it work with Mac or iPad?

Yes (it works as a normal Bluetooth keyboard). Remapping also works from a Mac with the browser app (Chrome / Edge). Settings are stored on the keyboard itself, so they follow it to any device.

Can I swap the switches?

Yes, it is hot-swap. But only low-profile switches of the Kailh Choc V2 type fit. Full-size switches such as Cherry MX hit the case.

What is the haptic feedback?

An extra: the left half answers your hand with a short buzz. For example, when you switch the Bluetooth target, you know it went through without looking at the screen. It can be turned on or off in the app.

Where do I ask when something goes wrong?

The app has a "Trouble?" section with fixes for common problems. If that does not solve it, any of these works (a human answers ばつべー ).
