Designing an anti-static enclosure for sensitive electronics
Looks like a good candidate for an Altoids tin (or other small metal enclosure - those just happen to be a handy size and common in the world currently - some decades ago it would be the pipe tobacco tins my great-uncle used.) 

Mind you, most devices are far less sensitive when fully constructed than when loose parts. But if you think it's particularly sensitive, might as well use a metal box (you can of course, use a die-cast electronic project box if little tin boxes upset your stomach - but they cost more and don't come full of sweets.)
