Contour Design today announced a new addition to its iPod case line, The ToughShell, a lightweight transparent shock resistant material to offer all-round protection and durability for Apple’s click wheel 20GB iPod, 30GB iPod photo and 20GB iPod with color display. “With the ToughShell, we have introduced a brand new product into our existing range of cases,” said Ketan Vora, a spokesperson at Contour Design. The ToughShell is made from enhanced transparent polypropylene, which not only provides protection, but is also designed to complement the overall look and feel of the iPod. The Contour ToughShell will be available the first week of November for US$21.95.
