There are five styles of mixtiles: Bold, Ever, Classic, Clean, and Edge.
Bold is the only style that was available when I made my review. It's a bit more graphic than the other styles and has thicker lines.
Ever is the softest style and looks more like traditional tile.
Classic is the default style and features thin lines with a slightly less pronounced graphic look.
Clean is the most minimalistic style and features virtually no lines at all.
Edge is the only style that includes an extra border around the edge of the frame that gives it a more polished look.
