Here I have found iPhone cases that fir the steampunk theme.
I think that this would be a good idea because in the present day iPhones are very common, and mixing the iPhone case with old materials such as cogs, and rust pipes etc, you can create an old effect on a new object that is seen very frequently and commonly requested.
I prefer the first case as it has a lot of detail with the paint and the actual detail with the cogs etc, this would be my style of choice because it is more professional and looks more eye catching as it is very rustic and unique.
