My Cyrill Color Brick came in today. I really like everything about this case. The case feels absolutely amazing. (It even passes the pinky test.) I’d say it adds the same amount of thickness on all four sides as the Apple leather case. From what I can tell, the Sheath, Apple leather, and the Cyrill Color Brick are the same width on the sides, but the Apple leather and the Cyrill Color Brick are both taller than the Sheath.
