Interactive Design - Personalize and customize your phone in a fun, fresh way. When you slip in a new Flipsuit Card into your case, your FlexWindow changes accordingly to match your phones new look. Motion Response - The new designs are not only interactive, but they respond to motion and touch as well. Move your phone around and see how the designs react. The LEDs on your Flipsuit Card now also light up and sparkle adding a new dimension of self-expression for you to enjoy.
