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.”
The cases that are on sale now are compatible only with the 2013 HTC One, but we’re expecting HTC to also launch similar Double Dip accessories for the All New One (which will be officially introduced next week, on March 25).
