HHI Wristband Skin Case for iPod Nano 7th Generation - Black (Package include a HandHelditems Sketch Stylus Pen)
If you're using it while watching tv, reading, writing, driving, typing or walking, it should stay in place just fine. However if you are running, exercising, riding a bike, cleaning or doing jumping jacks, I would not recommend anyone to rely on this to keep your iPod nano secure.
