This is quite an amazing cover, it offers great protection for your Samsung Galaxy Z Flip4, and the indents on the backside is not only cool - but also functions as a natural slot for your fingers when you're gripping the phone. But if you, despite the extra grip, accidentally drop the phone, then the way it's designed also offers extra shock absorption, as the dents catches and distributes the impact from the shock into the cover, guiding it away from the phone itself.
