Ways to wear it
One Tsumo. Two ways to wear it.
Wear it as a pin or a pendant, and move it between them as your day changes.
Concept designs, not working hardware. Images are concept renders made with AI, and size and battery life are still being worked out.

Pin
On a shirt, knit or jacket, and designed to move between outfits.

Pendant
On a fine chain, for days when a pin doesn’t suit what you’re wearing.
Concept render
Interchangeable finishes. Wear the color you want.
Swap the finish to go with your outfit or your mood. Every color here is the same Tsumo.

Swap and recharge
Use one. Charge the other.
Tsumo is designed so you can use one powered mount while a spare charges. When you need more power, move your Tsumo to the charged mount. You don’t have to stop wearing it to charge.
- Wear one while a spare charges.
- Move Tsumo to the charged mount.
- Put the other mount on charge.
Charging concept The battery isn’t in Tsumo. It’s in what you wear it with.

Pin
On the other side of the shirt, connected through two needles.

Necklace
At the back of the neck.
Charging concept. The mounts are planned to charge on a wireless pad. Where each battery sits is a design direction, and what comes in the box isn’t decided.
