The Clear (hard) is super thin, a hard plastic, and the case has cut-outs for the buttons on the phone. The Clear (hard) is .35mm thick. This case is made from a PP plastic.
Our Clear (Soft) case is going to be plastic as well, but it is more of a soft "goo-ey" plastic, for lack of a better term. The case is a little thicker but not by much. There are no cut-outs on this case and the buttons will be covered. This case also is more scratch-resistant, fingerprint resistant, and is more Clear. The Clear (soft) is just under 1mm thick. This case is made with a TPU plastic.
