The TuneBand for iPod nano 7th Generation provides a comfortable way to wear your device while running, working out, working in the yard, or walking around the block. It features a protective silicone skin that allows access to all ports and buttons (including the front and rear cameras), and a soft, elastic strap that fits most arms. We also include a screen protector that covers the front of the iPod nano. NOTE: This TuneBand is designed to work with a bare iPod nano 7th Generation *only*. You may have success installing our silicone skin over an existing iPod nano case, but this use is unsupported by us. Also, if the included elastic strap is either too long or too short, then please contact us at support [at] grantwoodtechnology [dot] com to arrange a replacement strap. We also mention this in the included thank-you card. If you prefer a TuneBand for iPod nano 7th Generation in another color (glow-in-the-dark or pink), then please search Amazon for "grantwood tuneband ipod nano 7th generation" and click on the appropriate listing. NOTE: If you are unsure which iPod nano model you own, then please look for a model number on the back of the device. It starts with "A", like "A1234", and appears in very small print. The iPod nano 7th Generation has a model number of A1446. Looking for a TuneBand for the older iPod nano models, like the 5th Generation (A1320), 4th Generation (A1285), 3rd Generation (A1236), 2nd Generation (A1199), or 1st Generation (A1137)?
