Care Guide
Purchased used and used for approximately 1 month. Operation has been confirmed.
With normal use, the battery lasts about 1-2 days. I used it without any issues by charging it daily while bathing.
There are no noticeable scratches or dents. The accessories are as shown in the photos: a complete set of charger and cable.
It will be shipped after initialization.
This is a used item, so please only purchase if you understand this.
This is an Oura Ring 4, US size 9, Brushed Silver model. It is a smart ring that helps with health management and sleep tracking.
The sleep tracking information was useful, but I am selling it because I have switched to health management with another smartwatch and no longer need it.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
