Also there's plenty of these glass-type display covers which are supposedly very good. (I have never seen one myself so this is just 2nd hand knowledge)
There should be something that more or less fits on top of the model-c, right? Because nowdays all phone devices look like each other...

(In reality I do not understand how those are supposed to work? How does the protective glass stick to the device glass? Do you need to use some glue or something?)
