## Description

Core Carbon RingsCarbon Fiber Ring with Fire Opal Inlay- Handmade- sizes 4-16

## Features

- 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 free exchanges until you have the perfect fit!
- Proprietary Nasa Technology in Each Ring - Having decades of experience with carbon fiber and composites, we invented a unique process for NASA that we use in every Core Carbon Ring made. The process allows for an extremely strong, lightweight, comfortable, 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.
- Glow - We use a Non-toxic strontium aluminate infused in our resin for the glow. Glow times vary depending on charge time and sunlight exposure/UV exposure. When charged with the included UV light for 5 to 10 seconds, the ring will glow strong for a couple of minutes then the glow will dim for one to four hours. It is necessary to be in a dark or dimly lit space to see the full affect of the glow. The ring can be recharged for 10+ years. Included is a UV mini light to charge your new glow ring!
- Satisfaction Guarantee - We want you to be completely satisfied with your new ring. If you are not for any reason, please contact us. We will be happy to exchange the ring until it is a perfect fit or it can be returned for a refund.
