Sizing - All of our rings are made according to US Sizing and are a standard fit ring. Please keep in mind, the band width can affect how the ring will fit. The wider band widths will sit on the fattier part of the finger making it feel tighter. We recommend with a 9mm or 10mm band width you go up half size from what you normally wear. We also offer on the house exchanges until you have the superb fit!
Proprietary Nasa Technology in Each Ring - Having decades of experience with carbon fiber and composites, we invented a one-of-a-kind process for NASA that we use in every Core Carbon Ring made. The process allows for an extremely strong, lightweight, relaxing, and truly unique ring.
Handcrafted on the Space Coast of Florida - Each ring is professionally and individually handcrafted giving you a one of a kind piece.
Satisfaction Guarantee - We want you to be completely satisfied with your recent ring. If you are not for any reason, please contact us. We will be happy to exchange the ring until it is a outstanding fit or it can be returned for a refund.
