MOTHER Bracelet - White Activity Tracker Body

This is a junk item (main unit only).
The item includes the main unit (junk), two types of bands, two starter kits, and a case. Individual sales are also possible, so please inquire.

This is the MOTHE Bracelet, an activity tracker that generates power from body heat, eliminating the need for charging.
I purchased this for my wife, but she barely used it, so I am selling it.
However, even though it wasn't used, when I tried to use it with a starter kit, the charging light turned on, but it stopped working, so I am selling it as a junk item.
This is being sold for those who can repair it themselves.

Also, I owned a black one but lost it, so I am also selling the case and bands for the black one. (The black band has already been sold separately.)

The bands included are the standard waterproof bands (black, white) and the separately sold accessory Strap Link (black, white).

The manufacturer's price is ¥43,780 for the main unit and ¥3,300 for each band.

Below is the manufacturer's description and link.

A multi-functional activity tracker that requires no charging, ideal for health management.
