I searched the forum but hadn't seen this posted before.
I was in Tesco's last night and couldn't believe they were selling these iPod nano skins for only a pound each!!! I oviously couldn't resist so i bought a couple. I am awaiting my nano to arrive as part of a student deal online so i haven't yet seen how they fit but for the sake of a pound i'll not complain.
They also cover the click wheel too so i was very impressed :)
I would guess they are made to fit the old style nano just incase you are wondering!!!
I have attched a pic i took using me mobile, they look the job if you ask me...grab em quick!!!
