## Description

THE RING - This ring has a modern flat band and a matte finish. The matte finish is extremely durable with a red/orange glow on the inside of the ring. The outside of the ring is a black carbon. The outside edges of the ring are finished so there are thin glow lines exposed on either side of the ring. Each ring is individually handcrafted giving you a one of a kind piece.    SIZING -  All of our rings are made according to US Sizing. However, 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.   PROPRIETARY NASA TECHNOLOGY IN EVERY 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.   THE 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 light 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 anywhere you are!   HANDCRAFTED IN THE UNITED STATES - Each ring is professionally and individually handcrafted on the Space Coast of Florida.   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 until the ring is a perfect fit or refund you for your order.

    Nice men’s ring
  

*by B***T on Reviewed in the United States on May 7, 2019*

Got one for my husband. It’s unique and my husband loves it. My husband is known for losing his rings, but he’s had his for at least a year now. He likes it a lot. It’s pretty cool when I glows:) not heavy. Good quality. Fit was correct.
