Thank you for viewing! We also appreciate the many repeat customers. Instant purchase is welcome. New Genuine product Blue brake sponge 2mm 10-pieceお得 set I often find that the thickness of the brakes I use for Mini 4WD is 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 #Brakes #BrakeSponge #MachDashMotorPRO #Mach #BreakingInMotor #Motor #MotorBreakingIn
