The white cover is milky and not fully transparent. This fingerprints are not visible. Susceptible the shell, however, is for scratches (eg. From fingernails). The slightly roughened surface, these are not too highly recognizable.
Both cases fit well and are flush. The attachment and detachment of the cases works fine. Sharp edges have no envelopes.
I doubt that the 0.2mm cases actually protect in case of a fall the iPhone from damage, since this material is simply too thin.
