Signal Blocking Faraday Bag — 3 Sizes, Phone to Laptop

A sealed Faraday bag in three sizes — from a 12×20 cm phone pouch up to a 35×45 cm sack that swallows a laptop. Fold the closure over and the conductive lining blocks the wireless signals reaching whatever's inside: cellular, Wi-Fi, GPS, Bluetooth and RFID. Choose Your Size 12 × 20 cm — phone, car key fob, cards, passport 25 × 28 cm — tablet, several devices, documents 35 × 45 cm — laptop, or a bag-within-a-bag for travel What It's For Stopping relay theft — seal your car fob so its signal can't be picked up and relayed Privacy on demand — a sealed phone can't be tracked, pinged or reached Travel and meetings — a hard, physical off-switch rather than a software toggle Isolating a device you're unsure about, so it can't report anything while you decide Details Material: Oxford fabric with conductive shielding lining Fold-over closure — no batteries, no app, no setup Test It in 30 Seconds Seal a phone inside and call it from another phone. No ring means it's working. Re-test now and then — seals wear, and a bag that isn't folded over fully doesn't shield. Honest Notes It works only while fully sealed. Take the device out and it reconnects within seconds. A Faraday bag is a radio control, not a malware control — software on a device can log data while sealed and upload it later.
