The Tough Series is a sturdy, yet thin Silicone iPhone 3G (S) case we carry. It comes in two colors, Pink, and Black. Both offer sturdy, form fitting protection. Unlike other silicone cases, the Tough Series silicone cases are not loose, they hug your iPhone 3G (S) like none other. This helps prevent dirt from getting underneath it to end up damaging your iPhone 3G (S) shell instead of protecting it. So, if you lead an active life style, or are in need of an iPhone 3G (S) case for those active occasions, then look no further than the Tough Series silicone cases.
