The lighter red side does not have the protective material on the inside, so it allows your mobile to have perfect reception. The darker side has the protective, silver-threaded material on the inside, which protects you from the hazardous radiation. So the dark red side should always face your body.
Fits any phone measuring up to 14x7 cm (iPhones, Samsungs, etc).
For other measurements, pop me an email and I'll see what I can do :)
