Good quality rivets and work as well as anything I've ever used. I bought these to use in my race car and they do their job well and look good. My only criticism was the way it was packaged or the lack of packaging. In the shipping box I received rivets and two stacks of blank DVDs. The rivets were only in the plastic bag and of course a rivet had to pop out of the plastic bag and pierce one of the DVD packaging. (See my photos) Luckily the rims don't seem to have been damaged by the rivets, but I think whoever sent this to me should have at least put the rivets in an extra pad before putting them in the DVD cases . Otherwise I have no complaints.
