For the red 12 phone, it is best to choose a black or transparent phone case, which can better highlight the red appearance and body design of the phone.
The black shell will make the phone more noble and mature, and make your phone look more professional.
The transparent shell can show the original face of the phone and protect the phone from collisions and scratches to a certain extent. At the same time, choosing a simple design style can also make the phone more clean and stylish. In short, everyone's aesthetic and needs are different, and the shell of their own heart is also a good choice.
