Choize Decompression Puchi Puchi Bubble Shell for Iphone 4/4s (White) Popping bubble wrap can be one of the most distressing activities which is also one of the few known upsides of the otherwise tedious unpacking and packing processes. The logic behind the rather unusual case is that the bumped surface of the case cushions your precious iPhone against various everyday scratches and accidental bumps and provides a virtual crash cushion to the phone as well. The surface of the case is designed to closely resemble the protective packaging thus allowing folks the pleasure of being able to pop bubbles whenever they want. The smartphone bubble popper case is made from four layers that include a sound layer and a bubble layer. Material: ABSSilicon
