This is my husband's. He doesn't seem to be using it anymore, so I'm selling it. It's a set of 17 items! I'll include a free Mirait! *There are only two 2mm aluminum lock nuts! I don't know the details, so please ask any questions in the comments. It may take some time to reply, thank you! #TAMIYA #Tamiya #Mini4WD parts Please understand that these items have been stored at home. Please take a look at my other listings as well. #5WGAgoods
