Check the listing for details. Oura Ring Gen 4 Size 8 Silver. Color: Silver, Condition: Used, Made in United States. Listed at 220.00 USD. I used this ring for about a month. It has some small scuffs on the palm side from normal wear. The ring charges and works perfectly. I prefer wearing it on my ring finger, so I'm sizing down.
