Beware of the fake "carbon fiber" clips that have been coming onto the market recently. Though they appear similar to the real thing... they are really fiber board and or plastic. They seem to have very clean cut edges (which is almost impossible to achieve with real carbon fiber) and have a little more weight to them. Picture below is one we bought that was advertised as REAL carbon fiber for $50. Don't get fooled. Buy real genuine carbon fiber clips.
