Abstract: A case for portable electronic devices having a magnetically shielded fastener is provided. The case includes a plurality of walls defining a cavity for slideably receiving a portable electronic device and a flap extending from at least one of the walls to enclose the device within the case. A fastener mechanism for retaining the flap in place includes a first fastener in a front wall of the case and a second fastener in the flap. The first fastener includes a magnet and a receiver configured for receiving the magnet and for redirecting the magnetic field generated by the magnet away from the device disposed within the case. The second fastener is configured from a magnetically attractive material. By shielding the magnet, the magnetic field generated by the magnet is redirected away from the device disposed in the case and focused towards the second fastener to maintain optimal pull force closure.
