High tech carbon fiber is joined together with the durability of Tungsten Carbide in this line of Black Carbon Fiber Wedding Bands. This comfort fit wedding band is a flat style with beveled edges.   The black carbon fiber is inlaid seamlessly into the center and then an extremely scratch resistant resin is applied over it to protect the carbon fiber from wear.   This style comes in 4 mm, 6 mm, 8 mm, 10 mm and 12 mm, which is great for couples who want a matching set.
