USBfever is shipping two additions to its line of iPod shuffle 3G accessories: a dual-pack of silicone cases, and a triple-pack of metal cases. The silicone package includes "frost white" and "smoke black" options, which guard Shuffles against bumps and scratches, along with moisture and dust. Access remains open to a player's ports and buttons.

The metal cases combine high-grade aluminum exteriors with neoprene lining to help prevent shock damage. The cases are also supplied with a 360-degree swiveling belt clip, which can be removed whenever necessary. Colors options in the bundle include black, silver and pink.

The silicone case set is priced at $6, while the metal package is tagged at $7.
