Protection bag when doing EFT or surge tests

Hi,

don't know if it's the right place for this, so apologize me. I used to use some kind of protection bag when doing EFT or surge tests. It was like two pieces of thick plastic with wires inside (so it was very strong but still flexible) and with velcro all around. So I could put the device I wanted to test inside, closed it with the velcro and do my test in safe conditions (if something explosed you're not burned).
So I'm looking for this kind of bags but don't know where to buy it. Have you any ideas ?
Thanks in advance for your answer(s).


Regards,

Frank.
