This cell phone bag makes your phone disappear from the network.
When you don't want to receive phone calls or be triangulated by Jack Bauer, just put your phone in this phone bag.
The case has two slots, one of which shields your phone. If you carry your cell phone in the other slot you still can receive calls.
The size of the phone bag is 85x35mm.
Gadget shop Brando offers the Black Hole Phone Bag for $12.
