OK the cases dont cause cancer but whats in them do!
i have been using camel snus seance highschool and i have allot of these little aluminum containers laying about
they come in 2 packages the thinner more stackable one (top) with a nice seal and thicker rounded op ones
there WONDERFUL for RF shielded small electronics ... the noise in there is nearly none! ... it has a nice all around EMF seal with a lip and is made of nice thick aluminum and is real easy to cut apart with a drill!
i have used Altoids containers before but these work much better!
snus sells for about $3 here a container but if you do chewing tobacoo this is a nice alternative (not to mention much cleaner and no spitting ...) if you want a nice RF case ... you can probably find these online empty for cheap!
i use them for everything from electronics to holding components safly to holding screws exc
and no they dont smell like tobacco ... they smell like mint!
and YES IM AWARE some people think this stuff is gross i dont need your comments!
PS: the snorter one has a "freshness seal" on the inside of a silicon rubber ring arround the inside of the top part ... its nice and air tight!
PPS: the shorter one also is far easier to open up if you dont have finger nails ...
Full disclosure: not telling anyone to get in to nicotine for these cases nicotine is bad and smoking is bad mmmkay?
