Handmade to protect the Pocket LOOX 720, the Proporta Alu-Leather case provides the robust protection of aluminum encased in elegant black leather. Both the Flip Type and Book Type cases provide internal storage for two MMC/SD cards as well as access to device functions such as stylus port, stereo output, and synchronization port. Also coming soon to Proporta – injection molded Magnesium Cases. Made from magnesium alloy the case is only slightly heavier than an ABS plastic case but is more than twenty times as strong because of the incredible tensile strength of magnesium.
