Ordered mine yesterday & it arrived today by free special delivery!
It contains two back pieces for the different depths of ipod, they should fit all types of classic ipods (fits the 160gb v5 very well). My last Belkin Acrylic case lasted 3 years, very durable.
The Belkin iPod Classic Acrylic Case is made from soft and durable material to keep your iPod in pristine condition. With a classic black finish, built-in screen and wheel protector, full control access, hard-wearing acrylic and a lifetime manufacturer's warranty, you'll not want to take your iPod out of its case!
