The Sena LeatherSkin case for the Apple iPhone 3G/3G S is a form-fitting case comprised of ultra-thin premium leather providing a soft layer of "skin" to gently protect the device from scratches. The fine, slender design offers a tight fit enhancing the curves of the device. The case is perfected to protect the iPhone with the most fashionable natural skin with no extra bulk. The LeatherSkin is individually hand-crafted from the finest European leather with Sena"s well-known quality and strong attention to detail. The case includes the unique design of the Sena Removable Ratchet Belt Clip System, which provides the advantage to use the case with or without the belt clip. The LeatherSkin is custom designed resulting in a smooth, form fit that offers critical protection. The leather for your Sena Case is individually constructed from the finest, full-grain leather. Like a fine handbag or leather shoe, a Sena case offers unparalled design. Due to the break in period and the nature of the fine leather, Sena designs the leather for the tightest fit to match the natural characteristics of the cases and the leather softens and improves over time. The leather adjusts to both the device and also to the individual habits of the user. It helps to gently break-in the leather by frequently using your case, and gently massaging the leather. Therefore, during the first few times using your UltraSlim case, if you feel the fit is very tight, please allow the leather a few days to adjust and soften for improved fit and functionality. You can shorten the break-in period by using the case frequently, but also carefully and gently.
