Make every paint matt

Today my nail subjects arrived, I had hoped that my would be okay, but that was not the case.
At first glance, everything looked ok: 50 Tips with nut and bolt in a clear plastic bag. But upon closer inspection, I noticed that the edges are worked enxtrem bad. This problem can be remedied by nachfeilen, I find but still stupid.
When painting the tips then joined the other reviewers already mentioned matt effect on, the paint has somehow contracted and was structured and no longer shone. I then tried the abzulackieren a painted tip again, but the color you get no longer all the way down. So return impossible.
Then tried to rework with a surface and Polierfeile, also did not help.
Take the tips now for experiments ago, but again I'm not going to buy me.
