Carbon Fiber skins are recognizable by their unique skin design. Each member of this family has been painted by using a carbon fiber hydrographic over a graphite base coat. Currently, there are four members within the Carbon Fiber skin family, however, due to them being added to the game at different points in time, each of them can only be obtained from different cs2 weapon cases.
In terms of price, it heavily depends on the skin itself, as well as its exterior and whether it has StatTrak attached to it.
