Mini 4WD Slim Mass Damper Silver, Black [Barrel dampers are not included. Instead, there are four silver and two black slim dampers, whereas usually there are only two slim dampers.] Unused, Tamiya brand, price not negotiable. I'm selling these because I only use barrel dampers and have a surplus of slim dampers.
