Mini 4WD HG Lightweight 19mm All Aluminum Bearing Rollers (Pink) x6 I opened the package but didn't use them. I'll also include 12 bearing roller spacers. I will put them all in a bag and ship them via Yu-Packet Post (photo 4). Since the package has been opened once, please refrain from purchasing if you are concerned about minor scratches. Please understand that this is a used item and no returns or refunds will be accepted.
