Worried about car thieves using signal boosters to steal your keyless entry car? It happens, but you can stop it with these Rivemon Faraday Bags. They're basically little shielded pouches that block ALL wireless signals – RFID, Bluetooth, WiFi, GPS, you name it. Just drop your key fob inside, close the flap, and it's invisible to hackers. No signal in or out. They're made from a cool carbon fiber material that's not only high-tech but looks really sharp too. You get two in the pack, in stylish colors (Bordeaux Red and Manba Green), so you can keep one in your pocket and one as a spare. They're super portable, about 3.5 by 5.5 inches, with a little hook so you can attach it to your keychain. They also have an extra pocket for a card or some cash. It's a super simple, affordable way to add a huge layer of security and peace of mind. Don't just leave your keys by the front door unprotected. Toss 'em in one of these and sleep easy.
