It is a repair logo for CC. Please use 3 months as a guide. It is a logo that is transferred by rubbing it from the top of the film. Dry transfer has a similar finish to silkscreen, but is expensive and difficult to personally create. The logo color is dark gray and is toned from genuine. Two pieces are a set.
