From Wensite: So much more than just a phone case. SafeSleeve for iPhone 12 & 12 Pro contains FCC accredited lab tested shielding technology that can block up to 99% of Radio Frequencies (5G, Wi-Fi, cellular, etc.) and up to 92% of ELF (battery, AC power, etc.) cell phone radiation from your iPhone. It also includes a built-in RFID blocking wallet and turns into a stand, all in one lightweight and convenient case. Box was opened but case is brand new, never used. It was too small for my phone (I have a 12 Pro Max).
