It fits pretty well on the Carbon 12

This is what it looked like moments after I installed the first one on my graph. Now my expensive Carbon 12 screen is protected. And even better it will bead away water spots from fish that splash on it when I land them on the front deck as well as rain spots. And your finger prints aren’t noticeable on the Graph Glass screen because it is oleophobic. It won’t allow dirt, oils or water to penetrate the screen. It cleans easily but so far I haven’t needed it.
