I am selling some items to organize my supplies, as I have about 1000 bags. As you would expect, these are genuine Tamiya products purchased directly from authorized retailers. They are not counterfeit. Also, I absolutely do not engage in the practice of swapping contents with counterfeit items, which is prevalent. Counterfeit color carbon parts are widely distributed. Carbon parts with a smooth (shiny black) surface are counterfeit. Please pay attention to the TAMIYA logo and the shape of the stars. Unopened, new condition Stored in a cool, dark place No discoloration or odors (tobacco, pets, incense, etc.) #Mini4WD Brake #Mini4WD Rear Multi #Mini4WD Multi #Mini4WD Carbon Rear Stay #95145
