Carbide Fiber band 8mm flat checkered. Size 9 

Carbon fiber isn’t a metal but rather a material made of tightly woven fibers. It is a strong material and can withstand rough wear and exposure without suffering too much damage. It is extremely lightweight and 3 times lighter than titanium, which is one of the lightest metals used for jewelry. Carbon Fiber is also hypoallergenic and isn’t known to cause any skin issues to the wearer.
