Strange, the icon pack goes under a different name in the Play Store than it does when installed. Here's a link to the icon pack.
Hope that helps!
The wallpaper is from something someone posted her a couple weeks back, I think it's from the comics. The icons are these https://play.google.com/store/apps/details?id=com.gau.go.launcherex.theme.circlewhite with the Apex launcher
Not material but I like minimalism too. Round White is what I use to compliment the Muzei and reddit wallpaper set up.
