Faraday Cage Sleeves

[Devonian]

MB, as LS suggests phones do a lot more than just make calls these days, they are in fact personal computers and can be used to store a lot of other information as well. Plus they may (??) still have GPS capabilities and I for example have a significant amount of OS mapping stored electronically on my phone which can still be used offline if the phone network and WiFi etc does goes down.

So for some of us there may be good reason for wanting to safely store such equipment........
