They are called iPod Shuffle Accents and come in packs of 4 for $19.95.
Each Accent is a small neoprene lined 100% anodized aluminum shell. The 4 pack includes a Red, Blue, Green and Pink shell. They look very festive don’t they?
They easily slide on and off and do not hinder access to any of the buttons, switches or the clip. I remember saying that the shuffle doesn’t need a case because it already has an aluminum shell. Well, after seeing these little covers, I have changed my mind. Mostly because they look so nifty :o)
