Constructed of an ultra lightweight polycarbonate material, the iSee inked nano 4G Zebra covers your nano in a hard protective shell without restricting the iPod's natural vibrancy. Just the opposite, the patterns of the iSee inked explode off the colorful backdrop created by the very nano encased within. And with a scratch resistant layer sealing the outside of the iSee inked, both the case and your iPod will stay looking fresh and new each and every day.
