A case for a portable electronic device such as cell phones, cameras, MP3 players and PDAs wherein said case includes material at the corners to provide protection to the electronic device. To reduce bulk at the corners and allow the material forming the case to conform with the contours of the device, the protection at the corners includes strips of material defining apertures there between. The apertures provide reduction in bulk and allow the case to conform to the corners of the device therein. Alternately, the protection at the corners can be provided by other structures co-molded into the corners of the cases. Such structures include material that is of a reduced thickness than other material used in the case, or structures that are formed to conform to the corners of the case. Such structures can be joined to the material forming the panels of the case by co-molding.
