The Black and White case is a 2 layer case that keeps your Blackberry Z10 well protected. The first layer of the case is a silicone with the second layer of the Blackberry Z10 case being a hardened shell to keep your phone protected. A decorative patterned exterior adds to the elegance. The Blackberry case provides full access to the charging port, volume buttons and speaker and camera lenses so your Blackberry Z10 phone is fully functional while in the case.
