This is the standard width (3/4inch) unidirectional high polished ring. The ring is very similar to our other uni-directional rings where the carbon fibers all run in one direction but this ring is finished off by hand with a high polish. The ring will shine in just the right sunlight and will amaze everyone who has a love for carbon fiber. Check out our other finishes to see which one is right for you! Available in standard ring sizes 4.5 through 13.5. Custom rings are availble upon request and are an additional $30. Ring width is approx 9mm
