Diverboxfor iPhone 13 Case [Shockproof] [Dropproof] [Dust-Proof],Heavy Duty Protection Phone Case Cover for Apple iPhone 13 (Blue)

Why don't some of the colors (yellow, pink, teal etc.) for the iphone 13 case come with the extras? (camera protectors, screen protectors etc.)

Does the red design have a black middle layer like the pictures? Or is it all three pieces are red like the others?

Does this case allow for wireless charging?

Is it non slip?
