Im gonna take a wild guess and go with valve spring retainers.My orthodontist gave me plastic ones back when i had braces...
Seriously though, retainers for what?
so who makes the shitty ones now.....?I use to make them for JG in the 90's If you do I would make should that they come or you hard anodize them first. Not sure if even i would use them as a daily driver. They were very light though
LOLso who makes the shitty ones now.....?
