Signal Blocking Cases for Mobile Phones

A lightweight, compact, and foldable mobile phone shielding bag that can be carried like a regular bag but provides shielding against mobile phone signals. The bag has a zippered box body with elastic sealing strips wrapped in conductive cloth. The inner surfaces of the box body have conductive linings. When the zipper is closed, the elastic sealing strips compress and contact the conductive linings to create a shielded space inside the bag. This prevents electromagnetic signals from mobile phones and other devices from escaping. The bag also has a foldable card pocket inside that seals when the zipper is closed.
