This design is something special indeed. Our 444 endurance ring features the massive 4x4 twill weave. Just look at those lines! This 10.5mm wide band truly shows how beautiful carbon fiber can be. The endurance (matte) finish is our longest lasting finish! Since the ring has a matte finish and a fabric outer layer it hides many scuffs that may show up more on a polished ring. We offer all of our rings in standard sizes 4.5-13.5 in whole and half sizes. We do not offer 1/4 sizes at this time. If you don't know your size please visit a your local jeweler and get sized. This only takes a few minutes and most jewelers are happy to help you even if you don't buy from them. Please do not guess on your size so that you can start wearing your new ring right away. This ring is made to order and usually takes 2-3 weeks to ship.
