Description

Thank you for viewing.
This is a Japanese-made smart ring released in December 2025.
It was purchased on January 15, 2026, and comes with a warranty.
There are minor scratches from use on the exterior, so it is listed as Slightly scratched and dirty.
We do not accept returns or complaints, so please refrain from purchasing if you are concerned about the exterior appearance.
I am listing this item because I personally no longer feel the need for it. The operation is fine.
