Smart Ring

New, Unused (Only for size confirmation)

Purchased on October 25, 2025, via mail order (NTT Docomo). However, I ordered the wrong size and it cannot be returned or exchanged, so I am selling it unused.
Please be sure to check the official website, etc., for sizing information (I cannot respond to inquiries about this).
Also, please understand that I cannot accept price negotiations at this time.
