Made from liquid silicone rubber, the Solo Loop features a unique, stretchable design with no clasps, buckles, or overlapping parts, so it’s ultracomfortable to wear and easy to slip on and off your wrist. Each band is specially treated with UV to give the band a silky, smooth finish. It’s also swimproof and sweatproof, so it can go just about anywhere you want to wear it. USED, but perfect condition.
