A new angle on carbon fiber style. The CarbonFG Ultra Forty Five takes the classic strength and sophistication of carbon fiber and gives it a bold twist — literally. With its distinct 45° twill weave, this slim 6mm ring creates a dynamic, diagonal pattern that catches the light and stands apart from standard designs. It’s eye-catching without being loud, engineered without compromise, and built to be worn anywhere.
Each ring is handcrafted from aerospace-grade 3K carbon fiber and weighs less than a gram. Its soft standard fit combines a flat inner surface with rounded edges, making it as comfortable as it is precise. Waterproof, hypoallergenic, and resistant to harsh chemicals, it’s ready for everyday wear — and it’s custom made to order in the USA with precision and care.
If you’re looking for something subtle, striking, and totally original, the Forty Five delivers. Order yours today.
