Black skins shown in a Matte Black iPhone 7 Plus. The Dark Smoke also looks GREAT if you want the "iPhone" logo to show through.
$5 each, now available at www.grfxp.com
and just as a comparison, here's a red skin on the same phone...
Since these two wallpapers seem to be impossible to find on the web, I recreated them both.
Enjoy!

Gray Lines Wallpaper...
I was really bummed to find out the Sandstone case that OnePlus released was only offered for the 6 and 6S. I really did love the feel of the OnePlus devices and would love to have a similar feeling case on my 6S Plus.
I've been working on this case ever since... hoping to have them in a week...
