it can only be imagined the sort of problems that would have been created if there were not some sort of identification for these last few cars. only draw back for me is the color i got the medium to dark color, and i found it too dark for me, so if you’re eye brow are darker than mine you should be good to go, but if you’re in between like me it’s kind of tricky! note: plugs cut with the grain will chip less and plugs cut across the grain will tend to chip more.
