Our amazing Bullet ring takes styling cues from the aerospace and racing industries with precision machined speed holes. The body of each Bullet ring is hand contoured and each opening is chamfered and de-burred inside and out using a proprietary process we developed just for this ring to ensure comfort. This ring measures 10.5mm across it's face. This 2x2 twill carbon fabric Bullet ring with 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.
