The Double Dip cases are made by HTC, and let you choose up to three colors that can be combined for a pretty colorful final look. Unfortunately for HTC One users around the globe, these cases are available just in the US - at least for the moment. According to HTC, the cases feature “a premium hard shell that guards against damage with a front screen overlay.”
