So you've just gotten yourself a spanking new iPod nano, and want to keep it in the very best condition? Enter Shimura with its full metal jacket specially made for the 3G iPod nano. Constructed from aluminum, this jacket will definitely prevent any unsightly scratches and nicks on your precious new nano. Unfortunately, you will need to open up the clamshell form factor each time you want to access the nano's controls, which could be quite a hassle. When closed, all the relevant ports are still accessible though.
