Corner protectors for iPhone 12 / 12 Pro / Max / mini

The 12 is the generation that reintroduced the flat rail, and every iPhone in this catalogue from the 13 onward inherits its corner geometry. If you want to understand how a Corners4 set seats on a modern iPhone, this is the body where that shape starts.

It also introduced Ceramic Shield on the front. The rear glass was not similarly upgraded, which is precisely the surface the corners hold clear of a table when the phone is set down face-up.
