Tunewear today announced two new leather cases for the iPod nano—the PRIE uni and the PRIE SilverBall. The PRIE uni is a black case with colored stitching along the front and back. It features a flip-cover that closes with a magnetic flap and a removable metal hook for attaching it to a belt loop or bag. The case, which also comes with a clear protective film for the screen and click wheel, is available in green, blue, and purple stitching. The PRIE SilverBall is identical in features to the PRIE uni, but features an accent of three silver circles located on the front of the case instead of stitching. Both cases work with 1G and 2G iPod nanos and will be available next month for $40 each.
