"Thin Red Line" Carbon Fiber Ring with an offset line and the bold look of stitched leather, while maintaining the comfort and durability of carbon fiber. 100% carbon fiber band. Beautiful satin black with no shiny coating to wear off. The colored bands go deep into the ring, so unlike most other rings, it will never wear off. The more you wear it, the tougher it looks. This a ring that can truly last a lifetime.
