::Update:: - The manufacturing fallout from making these fingerprint-loving docks was too high, even after a dozen process revisions, so we're not continuing making these after our second run. Recommend going with the Matte Black finish, it's super beautiful with all color iPhones.

To match the beautiful Jet Black iPhone 7, we made some special super-polished ElevationDocks with some special anodizing to match the finish. Apple may make the finish look easy with their robotic polishers in fluffy media and mid-anodizing magnetic polishing... we can tell you it's definitely not easy and have a lot of props to them for making such a beautiful and delicate finish.
For us, we are hand polishing them in 10 steps of coarse to fine media. And we iterated our anodizing process to keep it shiny, non-cloudy, and hard. And we put some turtle wax on for good measure. If you look really closely there are micro-size scratches in the finish, but they are not visible at useable lengths.
It looks absolutely stunning.
