Carbon and glowing fibers woven together for a ring that's hardly felt, but always noticed (even in the dark). This is literally the first woven glowing carbon fiber ring that actually looks like carbon fiber too. Carbon and glowing fibers woven together for a ring that's hardly felt, but always noticed (even in the dark).After 7 months of materials engineering and supplier collaboration... the first ever, glowing twill woven carbon fiber ring! To achieve a ring with glowing fibers, we weave a specially formulated glass fiber with the carbon fiber in order to produce not only the unique (stealthy) daytime appearance but a subtle green glow at night.
