The "Carbon K" is basically the "KLexus" design, also known as "Kia 3.0". The first and second images below... The first set is ALL metal skins, meaning they're ALL overlays. The second set is all metal skins EXCEPT for the front and rear emblems - which are replacement emblems...
The third picture is the "Vintage K". What's nice about the Vintage K is that it's an actual OEM design. The KLexus, Carbon K or Kia 3.0 were created to be similar to the Vintage K. In my opinion, and that of many other people, they're all nicer options than the "KIA" logo - and all being "K" emblems, they all still represent KIA...
To note, OVERLAY front and rear emblems don't come with the surrounding chrome edge - because they're made to fit in-between the chrome edge of the standard KIA emblem - so the edge is not needed...
