Thank you for viewing! Also, thank you to our many repeat customers. Instant purchase is welcome! New Genuine product Blue brake sponge 3mm Set of 10 When I'm into Mini 4WD, the thickness of the brakes I use tends to be uneven. I thought it would be easier to use if brakes of the same thickness were sold as a set. I'm sure many people feel the same way! I've put together brakes of the same color and thickness, so please take a look ^_^ Please refrain from purchasing if you are nervous or seeking perfection, as this is a personally managed product. *This product is not subject to discounts. #Mini4WD #Brake #BrakeSponge #MachDashMotorPRO #Mach #BreakingInMotor #Motor #MotorBreakingIn
